The Korkers Ice Runner helps you stay on your feet even when Mother Nature wants to keep you on the couch. Korkers designed the Ice Runner with 11 replaceable spikes-six in the forefoot, five in the heel-for ice-biting traction in the worst weather. The BOA fit system lets you adjust the fit with the turn of a dial, and all the BOA parts are guaranteed for life. Don't let snow and ice get in the way of your training. The Korkers Ice Runner cleat system gives you all the traction you need in a lightweight, form-fitting package.
