Choosing the correct skates size is a very important task and usually even more important than choosing the skates model! All of the 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.


The majority of inline 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 you European sizing like every shoe company has a slightly different fit and sizing – the same goes for the inline skate manufacturers. So, your standard shoe size might not be perfect as well but that is the perfect way to estimate your skate size. In the majority of the cases, the inline skate size should be either equal to your shoe size or no more than one size up or down from it. If you are indecisive about which one to choose, you could measure your feet according to the directions below and then find your size on the corresponding manufacturer specific chart that is listed on that page.

Important: Your shoe size is the defining factor! So if the measurement is showing more than one size up, something is wrong with the measurement! Almost never, the size of the inline or roller skates will be smaller than your shoe size. If your foot is wider than average, please go one size up than your shoe size. As a general rule, Gyro fits average.

We would be happy to guide you as well in case you have any further questions.

Please note: based on our experience the Gyro GFR GX7 skates are running half a size smaller compared to others. They do open up and adjust nicely just after a few hours of skating.

How to measure your feet?

  • 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 below. The “CM” indicates the maximum length of the foot in centimeters that will fit into that size. The US Size column lists the sizes found on the box.

The other option is to measure the insole of your other pair of skates or a pair of running shoes, that in case you are definite that you like their fit.

Sizing for Control over Comfort

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 Carbon boot 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 a built-in liner will have less adjustment room.
