5.11 Speed 4.0 Desert RapiDry 8" Boot | Dark Coyote | 1720044

When the heat rises from the ground up, the Speed 4.0 Desert RD is built to take the worst of it. The heat-deflecting insole keeps radiant temps from creeping in. Force Foam® at the heel absorbs the grind. Side zip gets you in quick. Outsole won’t slip, split, or quit. For the days when the heat climbs, the weight drags, and your footing has to hold.
