THE RUCKING SHOES "They&';re built for all-terrain, and I use mine on asphalt every day. I murder running shoes in no time, but I can put over 1,000 miles (with 45# minimum) and 2-3 workouts/week on my Mackalls before it&&';;s time for a new pair." - Jason, GORUCK Cofounder (former Green Beret) Rucking is the foundation of Special Forces training and the Mackall(TM) is an off-road rucking machine. Maximum versatility and maximum support in a low top trail shoe named in honor of Camp Mackall, the home of Special Forces training.
