The Loap FLAM men's ankle winter boots have an upper made of durable nylon and strong high-quality polyurethane. The lining is made of warm fleece, so they are pleasantly warm. The removable insole is also made of warm fleece and also of EVA foam material, which excellently absorbs shocks. The sole made of light and soft phylon absorbs all shocks and the thermoplastic rubber reliably resists pressure, so the shoes last longer. Durable upper. Fleece lining. Classic lacing
