Our updated gel-tech walker NEO 4 continues to provide an exceptional upper fit, improved breathable mesh upper and the advantage of a medial window. The addition of an ortholite sock liner provides an added touch of internal comfort and anti-microbial protection. The tried and true sole geometry features DuoMax and Trusstic system technologies to help support and stabilize each step, while the rear and forefoot gel cushioning systems and gender-specific midsole systems provide a well cushioned platform for the many miles of walking ahead of you.
