These boots feel very sturdy and protective which I love. Protection was my top priority with this purchase and I feel these boots will hold up to whatever challenge I put them to.
Having wide feet I was worried that they would be too tight, but the fit is just right. Maybe a bit snug, but the sizing in my eye seems a bit generous and there's enough room for my feet to not feel cramped.
I did have one issue with the lowest buckle on the boot. With my high arches/instep, the part of the buckle where the strap is held in place created a pressure point that made my feet/toes fall asleep after about 5 minutes of wearing the boots. Even leaving the buckle at the widest setting would not alleviate this issue.
I ended up taking some side cutters to the retaining bit of the strap and cut the protruding bit flush with the rest of the strap parts. After this mod the boots feel much more comfortable and I do not have issues with my toes falling asleep. The only concern now is that the removable part of the strap could "fall out", however if the buckle is left done up when the boots are stored there does not seem to be an issue.
All in all, I highly recommend these boots to someone with protection as their top priority and reasonably wide feet. If you have high arches/instep, be aware that there may be pressure points, but easily fixed through a simple "trim".
