Icebug PYTHO BUGrip
Here's what other sites are saying:
For advanced trail running in demanding conditions, try the PYTHO BUGrip shoes with carbide spikes for superb traction on wet, muddy and icy surfaces. Lightweight yet durable nylon and polyurethane uppers feature molded thermoplastic urethane (TPU) for structure and support at high speeds. Moisture-control nylon mesh linings transport sweat away from feet and dry quickly to keep you comfortable. Gusseted tongues keep out debris; reflective accents improve visibility in low light. Removable EVA insoles with ventilating perforations feature heel pad inserts for shock absorption and forefoot inserts for responsive toe-off. Molded EVA midsoles provide optimal cushioning and comfort; TPU midfoot supports help you maintain stability. Nylon shanks provide torsional rigidity ensuring stability and support on rugged terrain. Innovative BUGrip outsoles use durable carbon rubber and carbide tipped 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 both actions for solid traction.
