Have modified H.O., Connelly, D3 and Wiley rear toe plates a few times. Depending on foot shape you could be a size 9 street shoe with higher instep and wider...who knows...but need an X-Lrg toe slip so you can slide your paw up in there. A size Medium or STD (lrg) size can prevent you from getting up touching or on your rear horse shoe plus your instep could be pushed back. So removal and repositioning the strap forward or back is an option without cutting the plate. Check out the different rubber quality of the straps on diff barnds if you decide to try the RTP. Some are definately more comfortable higher quality and more pliable fixed units (non adjustable type). They hold you in better too. The most comfortable type that will fit the hole pattern on your ski is what you want imo. I have an H.O. Ski and use another brand for an RTP.
