Guys, I'm afraid breakage is inevitable. The plastic is just brittle. Initially I thought mine was gonna be OK (loose, but connected), but ultimately it broke just like everybody else.
To spiderbo, some of the mods suggested here just used regular TT feet shaved down. I've personally considered using a woman's feet instead to hopefully avoid that (foot being a bit too small relative to body is a non-issue here IMO), but I've not been able to get the foot out without potentially damaging the rubber part of the boot. I've actually rubbed some of the finish off the outside of the boot trying already. Don't wanna turn it inside out, either. So, he's just got a loose boot ATM.
