The Magnum Response III 8.0 SZ is a functional tactical boot that offers superior protection, optimal cushioning and unmatched grip on any terrain. The suede and nylon upper guards feet from the hazards of field duty or laborious jobs, and its lightweight design is perfect for extended periods of wear. The carbon rubber outsole provides traction on uneven terrain and is oil and slip-resistant. For all-day comfort, Mangum has included a removable contoured insole that delivers heel and ankle support to prevent rolling and torsional twisting. The fiberglass shank absorbs shock for softer landings and reduces foot fatigue. This model features a YKK side zipper for easy and quick removal.
