Skate Sizing

Choosing the correct skate size is a very important task and usually even more important than choosing the skate model! All high-quality skates will have a break-in period and will 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.

Please remember that the skates will feel the worst when you try them for the first time and from there the fit will only improve!!!

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


Most 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 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 the 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, a 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 manufacturer's 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.

Here is a great sizing video courtesy of Powerslide:



Our sizing advice is targeted at 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 going 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.

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.

2 reviews for Flying Eagle Phantom Carbon Inline Speed Boots 36EU


    I bought the Phantom Carbons on a whim. I’d consider myself an intermediate freeskater and aggressive skater, and was looking for marathon skates to improve my physical fitness. The clearance price put these within my budget, plus I love the Flying Eagle brand, so it felt like a risk worth taking. Given the rigid carbon fibre shell, these skates require more breaking in than your average skate, and the no-cuff design of the boot means that you’ll have to really work at strengthening your ankles and feet to get the most from them. But the challenge is worth the reward. These are beautiful, fast skates made with superior craftsmanship and a lot of style.

    It a crazy deal! very happy with the purchase. You should definitely heat mold these boots before the first session. It will dramatically enhance fitting and power transfer. I followed the heat mold tutorial on Powerslide Youtube channel and the results were perfect.
