We recommend choosing the same sock size as your shoe size. If your calf measurement falls outside the typical range for your shoe size, select the sock size that fits your calf instead
6.8W Saving
Over a flat 10-mile TT, at 50 kph, a saving of 6.76 W would save a rider over 3 seconds compared to our previous overshoes. Put another way, as this rider crossed the line in the One Overshoes, the same rider in our previous overshoes would be 41.8m or about 137ft behind you.
