How to Measure Your Foot
Place your foot flat on the floor against a wall. Measure the distance from the heel to the tip of your longest toe.
Always use the longer foot measurement for best fit.
Heel to Toe Length (in cm) is the most accurate way to choose your shoe size.

Sizes may vary slightly depending on foot shape and brand. This guide is for reference only.
Your racket is more than just a frame — stringing defines how it plays. The right tension improves power, control, comfort, and durability.
How String Tension Affects Play

Key Considerations

If unsure, always choose comfort first.
