Men's Korkers Icetrac Studded - Black/Orange IceTrac™ Studded Rubber Lug sole grips snow and ice while hiking, snowmobiling, or working outdoors. DETAILS: Traction: includes 16 ultra durable carbide studs per foot (32 total) for extra traction on icy surfaces. Sole Sizing: Outdoor soles come in whole and half sizes for both Men and Women and must match the size of your Korkers winter boots to function properly (e.g. Men’s Size 10 Boot = Men’s Size 10 Sole). Half sizes, select the appropriately-marked sole (e.g. Men’s 10.5 boot = Men’s 10.5-11 sole). Boot sizing can be found on the inside tongue label or on the original Korkers boot box or sole box.
