Customer Reviews
The Active88 Boulder is the perfect blend of fit, form, and function. This lightweight shoe is built for speed on roads and trails alike. After several years of being a repeat purchaser, I can confidently say it remains my absolute go-to for serious endurance racing. Handled the brutal terrain of the Grand Canyon Rim-to-Rim flawlessly. Powered straight up the steep, demanding ascent of Pikes Peak without a single issue. The upper materials quickly dissipate sweat to keep your feet dry. If you want a proven, durable racer that delivers reliable comfort under the harshest conditions, the Active88 Boulder is tough to beat!
Thank you so much for this incredible review, the amazing adventure photos, and your recent purchase of so many more pairs! Seeing the Active88 Boulder take on the Grand Canyon Rim-to-Rim and Pikes Peak is truly special. We are honored that it has remained your go-to shoe for endurance racing year after year. Your loyalty and support mean more to us than we can say!
