The Helix features a rubber "double toe" for increased abrasion resistance and durability, a composite safety toe shaped on TiTAN® last for non-metallic protection and a roomy fit, cement construction for flexibility and reduced break-in time, a padded top collar for comfort and a nylon shank for structural support. Anti-Fatigue Technology with conical geometry in the polyurethane midsole reduces shock and returns energy. Dual purpose top hardwear allows for instant lacing customization and a secure heel fit. The Rubber outsole features Ladder Lock outsole radius and is slip, oil and abrasion resistant.
The non-metallic, non-magnetic toe cap resists corrosion and meets ASTM F2412-11, F2413-11, 1/75 and C/75 impact and compression safety standards. The boot provides electrical hazard protection and meets ANSI Z41PT99, ASTM F21412-11, F2413-11 and ASTM F2892-11 standards to provide protection from open circuits.
