I just finished one ride with them. I bought them in 5 1/4", and the only difference I could find in riding with them was that it was easier to put my foot in when I mounted. On horseback, I couldn't feel any difference, other than it was wider than the 4 3/4" stirrups I had been using. Judging by looks, it ought to be very hard to get a foot caught in these. Based on one ride, I'd give the design a thumbs up! And they are just a few dollars more than the regular cheapie stirrups.
