A stable solution to year-round trail running on icy or muddy surfaces, ICEBUG MR3 BUGrip trail runners have carbide spikes for superb traction. Combination polyurethane/synthetic nubuck/nylon mesh uppers offer light weight, durability and water and snow resistance for all-season performance. Moisture-control polyester linings transport sweat off of feet and dry quickly. Reinforced, protective toe caps save uppers and toes from bumps and abrasion. Padded, gusseted tongues protect insteps from lace pressure and keep out debris; reflective accents improve visibility in low light. Removable EVA insoles with ventilating perforations feature heel pad inserts for absorbing excess heel shock. Dual-density EVA midsoles provide optimal cushioning, comfort and pronation control. Thermoplastic urethane arch and midsole supports help you maintain stability on rough terrain; Squish™ heel units absorb shock from impact. Innovative BUGrip® rubber outsoles use 16 durable carbide-tipped spikes to grip slippery and wet surfaces. Spikes retract into outsole lugs on hard surfaces and protrude on soft terrain—mixed surfaces combine the actions for solid traction.
