Crispi Men’s AT4 Boot

Mission-Ready Performance, Built to Move

The Crispi Men’s AT4 Boot is engineered for professionals who operate at speed—where agility, durability, and comfort are non-negotiable. Designed for law enforcement and military applications, the AT4 blends lightweight construction with tactical-grade support, delivering confidence across urban environments and rugged terrain alike.

Lightweight Agility with Tactical Support

Weighing just 1 lb 1 oz per boot (size 9), the AT4 is remarkably light without compromising stability. A balanced 2 Flex rating offers controlled support with natural mobility, ideal for patrol duties, rapid response, and long days on your feet. The speed lacing system ensures a secure, precise fit for quick deployment when seconds matter.

Durable Materials, All-Weather Protection

The AT4 features a water-repellent upper—available in suede (Coyote) or greased Nubuck leather (Black)—reinforced with run-proof nylon for durability and breathability. A protective leather toe cap guards against impact and abrasion. Inside, a 100% waterproof GORE-TEX® lining keeps feet dry while allowing moisture to escape. Underfoot, a Vibram® outsole paired with an EVA midsole provides reliable traction, stability, and shock absorption across varied surfaces.
