I ordered a half size down from my usual based on prior TP boots and also the sizing guide.  This is my first pair of steel toe from this brand.  When tried on, my foot didn't even fit all the way in.  Quickly found out it was because a misfitting insole was crammed into the boot that was too wide [and not long enough] and not laying flat.  On removal of the insole, the boot fits snug but fine with my foot right on the sole.  With any degree of padded sole being inserted, it jams at the toes right where the steel cap ends, which it should not do.  Time will tell if it will loosen up and I can eventually add adequate padding.  Aside from the sizing issue, the laces are a bit short as well, will need to get longer ones.

All criticism aside, the boots are the real deal and are in for a real beating, and for under 100 bucks who can really complain that much.

Just order a half size up from the sizing guide, and in my opinion you will be ok.
