The most comfortable flip flop you will ever wear! Unlike any other flip flop, the NuuSol Cascade is powered by Evasol™, a lightweight, soft and supportive material that actually forms to the shape of your foot! When you try these on, you will be amazed with just how comfortable they really are. Wear them around for a bit and you'll notice they are even more comfortable since the footbed has actually softened and your weight is dispersed throughout the whole footbed.
