(Alternatively you can get a temp copy of your plate made and have that in your window or attached to the rig itself to avoid the problem completely) They seemed OK at first but in actual hiking conditions they are too small, too short. very heavy to walk with. The first one I received was defective, it had a bleached/burnt mark on it. However, since after three months, they were somewhat dirty and stained, I threw the shoes in the washer and drier with dark clothes and they came out fine. My husband LOVES Crocs. I guess people are saying they are small because they like extra room at the end of there sandal. It is good for medium sized parties of around 50-100 audiences. After a bit of adjustment to the shapeable hooks, I got a pretty good fit. I looked up the PowerTec brand T-track and it appears PowerTec has 2 different internal dimensions that would suit these larger Ts.
