What puts the wonder into WonderWelly? We set out to turn an iconic silhouette into the world's comfiest rain boots with our biomechanically engineered technology. We've contoured the sole to evenly distribute bodyweight, filled the hollowed-out heel with our innovative honeycomb design that absorbs the impact of every step, and placed high-rebound micro ‘springboards' in the forefoot of these lightweight waterproof boots to help put a spring in your step. Now with our updated design for even better performance.
