Obviously, a large portion of any climbing wall should focus on feet. I have these on vertical and overhanging sections of my wall and they perform superbly on both. I also use these in several places as push-off feet to move out onto my roof. The little ridges are perfect for gripping into shoe rubber. Honestly, my feet slip off of a lot foot jibs because, well, I'm not a 5.13a climber, but not these. These are like little foot anchors - I love them. Atomik used to call these "Armadillo Feet" but I'm sure most people were like "What the heck is an Armadillo?". If your from the south, then you know. Scaled Tech Feet sounds way cooler - no offense to the lowly Armadillo. At about $2 each -- dang -- get as many as you want!!!
