I have heard of this issue and assumed it must be the right (or wrong) type/size of boots as I have never had an issue with getting hung up in the stirrups on any of my Pro's (2011, 2013, 2015) I did have an issue with the stirrups last year on my 2018 Axy, twisted my knee and hobbled for 3-4 weeks. I got hung up again this season (Dec 28th) but this time I broke my ankle.. I cut the toe piece off today, as it doesn't look to be structural. If I find I miss or need them (doubt I will) I'll weld them back in 1"+/- higher.
