I had the 105 mm patemt-Tribute Sandals in a 35.5 (and I am usually a 35 in the regular leather, and can fit into the patent 35), but I actually went a whole size up, just so I could put insoles in them without squishing my toes (as my feet are not narrow), because the were more comfortable. However, I think I am really pushing it with a whole size up.
As for the Tribtoos, I have the shorter heel, and in the patent, I went 1/2 size up, but they are the slingbacks, and they apparently run a bit smaller than the regular leather.
Frankly, my patent Tribtoos have not stretched, nor have any patent shoes I have.
I hope I was somewhat helpful? If not, ask more questions !
