The Spyres are lightweight boots with a stiff forefoot fl ex. The uppers have suede in the lower half – good for protection – and nylon in the top half. The heel counter and toe bumper are hard. The fit is on the narrow side – I can just wear them with thin socks. The sole grips okay but does clog easily, especially at the heel. Cushioning is fine under the heel but not so good under the forefoot. The footbeds are quite supportive and better than most.
