Features of a walking shoe
Achilles tendon protector. Reduces stress on the Achilles tendon by locking the shoe around the heel.
Heel collar. Cushions the ankle and ensures proper fit.
Upper. Holds the shoe on your foot and is usually made of leather, mesh or synthetic material. Mesh allows better ventilation and is lighter weight.
Insole. Cushions and supports your foot and arch. Removable insoles can be laundered or taken out to dry between walking sessions.
Gel, foam or air midsole. All of these materials cushion and reduce impact when your foot strikes the ground.
Outsole. Makes contact with the ground. Grooves and treads can help maintain traction.
Toe box. Provides space for the toes. A roomy and round toe box helps prevent calluses.
