What puts the wonder into WonderWelly™? Using the science of biomechanics, we set out to turn an iconic silhouette into the world's most comfortable rain boot. We contoured the insole to work with your natural alignment, filled the hollowed-out heel with impact-absorbing honeycomb cushioning, and put high-rebound 'springboard' ridges at the forefoot to propel you forward with each step. These game-changing waterproof boots are also ultra-light, flexible, supportive. Unbeatable for long walks, here in the short version.
