Retailers' Descriptions

Here's what other sites are saying:

A dry/stable solution to trail-running on wet and icy surfaces, the waterproof ICEBUG MR4 BUGrip trail runners use carbide spikes for superb traction. Combination polyurethane/micro leather/nylon uppers offer lightweight durability and water- and snow-resistance for all-season performance. BUGdri® waterproof breathable membranes are seam sealed to prevent seepage but allow internal condensation to easily escape. Moisture-control nylon mesh linings transport sweat away from 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 arches and midsole supports maintain stability on rough terrain. Innovative BUGrip® outsoles use durable carbon rubber spikes to maintain grip on slick and wet surfaces. Spikes actively retract into outsole lugs on hard surfaces and protrude on soft terrain; mixed surfaces combine these two actions for solid traction.
