These women's premium athletic shoes are made by Asics. They have a ComforDry sock liner that keeps the wearer?s foot cushioned and has anti-odor properties. The shoes have Gender Specific Cushioning, which has a lower density top layer in the midsole. The shoe?s Impact Guidance system enhances the foot?s natural gait between heel strike and toe-off. There are two layers of memory foam in the heel. The Guidance Trusstic system and Guidance Line combine to help gait efficiency and midfoot structural integrity.
