babysmurf,i assume you ride english.have you tried raising your stirrups a little and keeping your heels down?
For my english saddle I have the leathers one hole past "correct" length, which still doesn't work well for me. (My knees are shot, and will cramp up if I have them at the "correct length") But like a good horsey person, I suck it up, LOL
I have a 38" inseam, so my legs are kind of on the long end of the spectrum. And not to sound self-promoting, but keeping my heels down is actually one of the things that I do really well. At the correct length, if you are level and looking at me, my heels are even with the bottom of the barrel (haha, that sounds funny) anyway, to make contact I have to bring my leg back and heels slightly up otherwise my feet are at a really sharp angle, which stinks with field boots on. I use longer spurs (@ 2") which are curved in and has helped close that gap.
