I have never liked traditional running or cross training shoes because they feel heavy, clunky, and restrict muscle movement and needed toe control. When I saw these I couldn't wait to try them and they have really made a difference on how I feel during and after workouts. I do not do long distance running but use these for cardio, jump rope, sprints, weight lifting,etc. I have a high instep and what I call duck feet. Traditional shoes strain my arches & make my feet cramp. Since using these my feet do not cramp while working out and I can move quicker for agility activities. They are light weight and leave the ankle free (if you have bad ankles you might wear a brace). I highly recommend these if you want better traction, light weight shoes, more comfort, and a barefoot feel. If I had the money I would stockpile these!
