According to Mayo Clinic, effective walking shoes have an Achilles notch, ankle collar, upper and insole. Other key features include a midsole, outsole and toe box for maximum toe space and comfort.
The Achilles notch reduces stress on the Achilles tendon and the ankle collar provides cushioning and ensures correct fit. The upper, which holds the shoe on your foot, is more effective for walking when made of mesh. The insole, midsole, outsole and toe box provide the cushioning, support and traction needed when walking. Quality walking shoes often include a gel pad to reduce impact and a roll ball for foot stabilization, states Mayo Clinic.
