I have this same pad and same size. Im 5 10". I use the bungee toe ties and tight, i have the boot strap not even tight what so ever, I strap the others normal and then the top strap I strap up higher. If I put the top strap lower or down I will slide off the knee landing. So I keep it up. Makes all the difference for me. I also have a set of V7s and its the same. I went with the suggested Vaughn sizing on all sites and this is what happens with me
