We give our feet teeth on winter runs with the Icebug Arcus 2 BUGrip GTX Running Shoe. The outsole's dynamic studs bite into snow and ice, as well as flex with our stride, so our strikes are solid and our transitions are smooth, while the lively BUGforce midsole foam energizes our toe offs. As we stride through snow and slush, the wet, wintry terrain is hard pressed to soak our feet with the GORE-TEX ePE Invisible membrane barring it entry.
