Having been a inov8 Xtalon 210 user for years I decided to try a pair of Walshies just for a change. However, they have arrived and are quite tight. Do they need 'running in?' or have I just purchased the wrong size? or has anyone got any tips to ease the tightness. (I have already taken the insole out which helped) I went for the same size as my talons but I find I can run long straight out of the box with those. Any thoughts welcome.
