Very happy to have received my KEYONE last month 🙂 It's such a life-changer during sprint sessions, especially in the middle of winter when you have to get back out of the cold and rain between races. Very easy to use, they are perfectly adapted to the size of my spikes, are very comfortable (you feel like you're wearing real shoes when you move around) and take them off very quickly. They protect the tips very well and help avoid disasters in the bag (pierced water bottle ^^). In short, everyone should have their own pair of KEY ONE 🙂
