Skate Sizing

Choosing the correct skate size is a very important task and usually even more important than choosing the skates model! All high-quality skates will have a break in period and would adjust over time to the skater’s feet. Some will take longer and some shorter, but while you want to have a comfortable ride you do not want to have the skates too loose… The correct fit will determine much more than just the comfort - it will define how much control, power transfer, and agility you would have while skating, and even would affect the balance.

While various skating styles and skaters themselves have different preferences, below are the general instructions of how to determine the perfect fit for your new skates.


Most of inline and roller skates are manufactured and sold in European sizes (EU), so your US / UK sizing could be a wrong idea to use due to the conversion inaccuracies. Furthermore, even if you know your European sizing, every shoe and skate manufacturer has a slightly different fit and sizing, therefore your standard shoe size might not assure a perfect fit but that is the best way to estimate your skate size. In any case, the inline and roller skate size should be either equal to your shoe size or no more than one size up or down from it.
Based on our experience, the best way to determine your skate size is to take a look at your current pair of skates and/or running shoe labels for MM / CM / MP / MONDO numbers. These numbers are indicating the maximum foot length that will fit into the pair, while MM shows the measurement in millimeters and CM/MP/MONDO is centimeters. Having these numbers along with the EU sizes from these shoes, you will be able to determine the size of the skates that you need by looking into brand or model specific sizing chart (usually located in the Sizing tab under the skates photos or as one of the product photos). If cannot be located, please send us an inquiry and we gladly will help you out!
Important: Many shops are recommending measuring your feet to determine your skate size, but we have found that this leads to too many mistakes and do not recommend that. If after following the instructions above you are finding yourself stuck in between two sizes, you could measure your feet according to the directions below. In this case, your shoe size is still the defining factor, so if the measurement is showing more than one size up or down, something is wrong with the measurement! If your foot is wider than average, please go one size up. Usually, Seba, FR, and Adapt skates fit wider than average, Powerslide and K2 average, Flying Eagle and Rollerblade average to narrow...

Still, want to measure your feet? Here is how to do it:

You’ll need paper, pen, a flat wall and, if possible, a buddy to help. It’s best to measure your feet later in the day after you have been on them for a few hours to account for swelling.
Find a hard floor with a flat wall. Tape a piece of paper down so that it touches the wall. Stand on the paper in bare feet, with your heel just touching the wall.
Have your friend take a book and place it so that it just touches the tip of your longest toe. Mark the spot where the book meets your toe. Do this with both feet and use the larger of the two measurements. Measure your foot length in millimeters, if possible. If you measure in inches, be sure to measure in 16ths of an inch.
Choose your size from the manufacturers sizing chart. The “Max Foot Length” is the longest foot measurement that will fit into that size. The US Men’s column lists the sizes found on the box.


Our sizing advice is targeted to a freestyle or dance skater who wants a very snug fit in their skate to enjoy maximum control. Our instructions will give a fit that prioritizes control over comfort. If comfort is a higher priority, or if you have an especially wide or oddly shaped foot, you may do well to choose a slightly larger size. If you are near the boundary between two sizes, you would probably be better off to go with the larger size in case you prefer comfort over control.
Notes about Width
In general, the Plastic Boot skates with a built-in liner have a narrower fit through the foot, while the boots with a removable liner and soft boots have a somewhat wider fit. The Carbon is a bit wider through the toe box than the plastic boot skates because the carbon fiber boot has less flex. As a rule of thumb, skates with built-in liners and "regular" liners will have less adjustment room.
We gladly will guide you in case you have any further questions. Email us at [email protected]

To help you better, please include all the sizing information off one or two pairs of skates or running shoes that you currently have including EU/US/UK/MP/CM/MM/MONDO, etc...

Flying Eagle Sizing Chart

Based on our experience, all of the Flying Eagle skates are running about half a size smaller than the shoe size as well as average in width. They are usually not the best choice for skaters with wide feet.

Please note: your shoe size is the defining factor! Almost never, the size of the inline skates will be smaller than your shoe size. If your foot is very wide, please go one size up than your shoe size. Flying Eagle Sizing ChartIf you want to use the foot length information to narrow the sizing down, the best way is to get that information from your running/sports shoes sizing label. Almost always they will have one of the following: MP/MONDO/CM – length in centimeters or MM – length in millimeters.

    Superb Skate

    After watching the inimitable Bill Stoppard’s YouTube review of the FE Falcon, I immediately decided I had to check out this skate, especially because of the nice price. But I decided instead to get the slightly more expensive FE F7 Optimum, and it’s a decision I definitely don’t regret!

    For the price, they’re light, easy to get on and off, extremely comfortable, and very well made. I’m more of a fitness than a freestyle skater, so I found the 243 mm frames just a tad too short and responsive, so I put on a pair of 273 mm frames and I’m really rocking these skates.

    Kudos to Flying Eagle for a superb product at an excellent price point!

    fantastic urban skates

    solid and durable, the hardshell can take a beating. Perfect for urban skating if you want a pair that will last you long and can that the shock of bad roads.

    Great skate all around! Super comfy!

    My first pair of Flying Eagle skates and couldn’t be happier with them and Pro Skaters Place. I’ve already placed more orders with them due to their fast turn around time and they have the best selection of FE skates as well as high end products. F7’s are very comfortable right out of the box. I wore ankle socks my first ride in them and didn’t regret it one bit. Frames are strong. Bearings are very smooth and they look great! Thx PSPlace!

  4. Andrew

    Best skates for the price

    I bought these to start skating again around urban areas while doing some jumps here and there. Pavel was a pleasure to deal with at PSP. I am definitely going to be buying the Supersonic frame for my F7’s.

    watching Bill Stoppard’s on YouTube reviewing of the Falcon f6.i decided to get the F7 main reason because i like the F7 color. i purchase zetrablade blade 80 from amazon paying almost $100 but i regret because of posture/alignment issue comfort was so,so. see with these Falcon F7 skate you can tweak skates to your likeness.i will recommend pro skater place to start stacking on parts like axle,liners for the eagle brand.i am a novice but i have improve a lot using these skates.,very durable,comfortable,good shock absorbing.well that all .have a great day and STAY LOW standing Tall is for suckers:)the bill man stop-hard not Stoppard lol .Also i will recommenced before sending the skate out to customer not to rocker it beginners will not no and find it very hard to get balance/control on them thinking something is wrong with skates.that it then.

    These skates are very impressive. The liner is comfortable and the laces and buckles are supportive without being too difficult to tighten for a good fit. The buckles seem durable. I wanted to try something different, so I got the optional 3x110mm supersonic frames with Twincam ILQ9 Pro bearings and Gyro Valkyrie Red 85A wheels. As a result, these skates are very fast and highly maneuverable. I ordered a size 42 and I agree that the skates run a half-size smaller. Overall, I’m impressed with these skates and would recommend them for freeriding.

    Love them

    This are my first pair of skates ever so I don’t have any criteria to compare them against, so I’m going to share my experience with them.

    Size: I wear EU 43 shoes, but I read that its better for skates to be half size smaller so I ordered EU 42 which resulted to be a bit tighter than I like, but depending on how I lace them they are comfortable.

    Wheels: I’ve been learning on rough asphalt and after 30 hours I can see the front and back wheels being deformed considerably (probably due my bad strides and lack of edge control) so I suggest if your place is like mine order an extra set wheels as well..

    Speed: Though my technique is not quite polished yet I can tell that bigger wheels makes the difference while attaining and maintaining speed. The standard 80mm are very smooth though, they don’t transfer as much vibration from the surface unlike skateboards for example, which is great!

    Durability: You can tell that this skates are made to last, very sturdy and light, sure they can take a beating without problem.

    So far I’m very happy with this skates I’ll definitely buy another Flying Eagles again.

    Great skate, beware if you have high arches

    I’ve been skating for twenty years, mostly urban skating. I loved everything about these skates except for one issue.

    I have high arches. The hardshells themselves accommodated for that fairly well with flexible material around the laces, but the liners did not. They were cut too low and the shells dug into my ankle bone.

    I was able to fix this, albeit imperfectly, with some gel pads, and then later a pair of intuiton liners and the are now my favorite skates. Just be aware that this may be an issue for you if you have high arches.

    Amazing Skates

    My first pair of expensive skates and I love them. Very comfortable skates and really good for a beginner like myself. You wont be dissapointed if you buy these skates. You will love them. Very much appreciate the staff of that helped me out with to figure out my size. They were right on the money with the size they recommended.

    Best value for the price

    I chose these because I am already familiar with these boots and liner. I have the Flying Eagle F110H which is the same boot just different color, and this time i was looking for 80mm stakes. They are very comfortable right out of the box, no breaking period for me. The quality is very good, the frame is the strongest in the market and its rockerable so you get a good value for the price. it will come as rockered when you receive them, so be careful if you are a beginner. I would highly recommend proskatersplace to start selling the F7 liner because they are one of the best liners out there. I contemplated getting other boots like F6S but i heard they are narrower than these, i also wanted to try the Rollerblade twister X but they do not have the rocker option and i was not familiar with the fitting. So i stuck to what i know and i do not regret it.

    In LOVE with these skates

    These are hands down everything I have ever wanted in skates! They can do it all! From slalom to a marathon distance. They will have you shredding in comfort!!

  12. Carsyn Cassidy (verified owner)

    The boots are very comfortable and can be worn all day. They handle my commute with ease and they’re fun to play around on. I’m still learning some skills and they are definitely durable and can take a beating

    The one thing is when I got them the wheels were on WAY too tight making the bearings stick so I had to loosen them off. This may have also affected the bearings’ longevity.
