Wolverine DURASHOCKS insoles add energy through every step. DURASHOCKS combine a host of energy-dissipating features into one powerful footbed, ready to cushion your feet during the grind of today's demanding work environment. A high-density base layer distributes weight while a low-density layer of EVA foam cushions the impact from heel to toe. A GEL PAD under the forefoot and heel places special attention on the areas of highest force. The base design allows the footbed to flex and continue providing comfort no matter your body position. Your hardworking feet deserve the best technology, and that is exactly what this DURASHOCKS insole provides.
