WAA is a European brand known for its very slim fit, which differs from North American sizing standards. We strongly recommend consulting the provided WAA sizing guide. As a general rule, choose at least one size up from what the guide suggests. If you are at the upper end of a size range, consider going up two sizes.

The Trail Runner Store does not assume responsibility if the sizing is still not a perfect fit for you.

Whatever the season, the Calf Sleeves protect you and guarantee better muscle performance. 

The Stadytape® strips provide targeted muscle support so you can focus on having fun and performing. Calf Sleeves protect your skin when you decide to run off-road: creeks, forests, rocky terrain ... Moreover, they provide ideal thermal protection when temperatures get cold or ideal UV protection when the sun is shining !

Its Icefeel technology allows you to stay cool and dry by evacuating perspiration away.
