I have to agree with 5 shot on this one. I love the new stirrups, however, they are a bit on the flimsy side. I don't have a problem with acending and decending. I use the new mini-viper X4 and I have size 9 1/2 feet so I don't have as much issue with the room. I too feel they will improve upon this idea next year as well. It sure beats the heck out of the old strapping method IME.
