Icebug MR4 Dry BUGrip
Here's what other sites are saying:
The MR4 Dry BUGrip by IceBug shrugs off ice and snow with spikes that bite hard into frozen surfaces but conveniently push up harmlessly into the carbon rubber sole when you're running on clear pavement or hard trails.

We're still not 100% sure how the Icebug Men's MR4 BUGrip Trail Run Shoe packs so much performance into such a small package. The carbide steel BUGrip studs turn slippery trail runs from hellish to heavenly. When you put weight on the shoe, the studs recede into the sole the more weight you transfer, the more the studs recede. On slick surfaces they protrude for better bite, and on asphalt and concrete, they sink in. The studs work independently from each other, so they can match even the most varied terrain. Above this futuristic sole, Icebug laid an anti-pronation EVA midsole with a TPU stabilizer to cushion and help correct your stance. The MR4's upper consists of PU coated micro leather with a 10K-rated waterproof BUGdri membrane, so you can slosh through snow, rain, and streams and maintain dry feet. *Not for indoor use.

A dry and stable solution to year-round trail-running on wet and icy surfaces, these waterproof trail-runners use carbide spikes for superb traction. Combination synthetic leather/nylon uppers offer lightweight durability and water- and snow-resistance for all-season performance. Moisture-control nylon mesh linings transport sweat away from feet and dry quickly. Reinforced protective rubber toe cap saves uppers and toes from bumps and abrasion. BUGdri® waterproof, breathable drop liners are seam-sealed to prevent seepage but allow internal condensation to easily release. Padded, gusseted tongues protect insteps from lace pressure and keep out debris; reflective accents improve visibility in low-light conditions. 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 (TPU) 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 harder surfaces and protrude on soft terrain--mixed surfaces combine these two actions for solid traction.
