i used the same as the strapping for the stickies. it worked well but had some issues with the shoulders wanting to spin on my arms. i think that possibly adding a strap across the front would have secured it better. the boots held up sooo well. i was really happy with them being really flexible and comfortable and we were walking around for about 12 hours in them and they held up well and our feet didn't hurt or anything. going to make templates for them and put them up in case others want to make them.
