I have Diamonds on HP RIP excellent pads with great toes grip, Cabrinha Syncs just crap in comparison, but they are not soft, my toes used to bleed every time after 4 or 5 hrs session,( because of the straps) to give them a rest I had to switch to my other board with OR Bliss pads in my opinnion Bliss are most comfy with good grip but Diamonds do beat them as far as toe grip is concerned, Ian Young should help you with those.
I dont have bleeding toes any more every time I ride HP RIP I do plaster them very well

If you use diffrent straps with Diamond pads you wont have that problem anyway.(
