It fits perfectly when I ordered my size! Maybe a bit snug, but a comfortable kind of snug! And still lots of space for my toes, which I was hoping for.The back of the heel part of the boot, however, is hard and presses up against the back of my foot. [EDIT: The boot has broken in and it’s okay there now.] Another reviewer had the same problem, and got blisters. (I haven't had a workday in these yet.) But the other reviewer solved the problem by putting some 3x3 inch padding at the back, and from what I can tell, that should work for me too. I'm going to do that today or tomorrow. Next time I order a pair of these, I might go up a half-size to see if that solves it, but I'm worried that might be bad for the rest of the fit.[EDIT: I bought 1/4” Neoprene foam padding from XCEL, but those didn’t work because the adhesive wasn’t strong enough to handle the wear of putting on and taking off the boot. However, the back heel part of the boot has broken in, and it’s not nearly as uncomfortable as it was on the first day.]I'm nevertheless very pleased with the purchase, and I'm keeping them:- Great for the price- Great fit (except for that heel issue)- ASTM F2413-18 approved for the Toe and for EH (Electrical Hazard) so I'm insulated from the floor. The product pictures show that the boot is also ASTM F2413-18 PR (Puncture Resistant) but I don't see the PR label on the inside of the tongue—only the Toe Impact & Compression, and Electrical Hazard. It's kinda sketchy that PR label isn't there, but hopefully that's only a printing oversight.- Love the zipper; YKK zippers are quality. I would hate having to tie my shoes all the time, especially for taller boots. The top two are speed lacing, so not that bad. The lace eyelets seem to be thick plastic, not metal, but they have no give, are sturdy, and I'll be using the zipper anyways.- Grippy, thick rubber soles, but you're not going to be able to resole these shoes like you might with more pricey leather boots like Red Wing or Thorogood. In the long-term, if you're down to take care of your boots, those brands are probably the better option.- WaterproofI'm personally still hoping on some workboot that fits all my requirements of: good fit; ASTM F2413-18 for Toe, EH, PR; zipper side or BOA; waterproof; union/worker-cooperative-made; vegan leather; and even zero-drop / barefoot. These OUXX seem to come very close, just missing the last 3, but hey, sometimes ya can't have it all.[EDIT: If you want a more zero-drop feel, you can take out the insole and order a flat insole.]
