I bought these for my fiance who works outdoors doing all sorts of crazy things in every weather condition imaginable. I asked him about how he likes the boots, and he says "I bought a size 8 so they would be wide enough for my feet. If I had bought a size 7.5 (his actual shoe size), they would have been too narrow." So if you usually prefer a wider shoe, you may want to consider going a half-size up.He also says: "I wear them all day. I want to get like gel insoles cause they aren't the softest to be just standing on. I've worn them 10-14 hours and only start hurting near the end but that's just fatigue." So there you have it. You can wear them all day, they aren't as comfortable as tennis shoes but that's how boots are, so if you have sensitive feet or know you have had issues before, you may want an insole of some kind. Having said that, he wears them for very long periods and has no issues with his feet (no bunions, no blisters, nothing like that).They aren't made specifically for arch support, and he says "These don't really have a huge arch support. Just enough for me to know I have it there but nothing that really sticks out if you have high arches." So there you go.Having said that, he got very sad when the shoes started to scuff because he said they look so nice. ;) That's what happens when you work! But yes, he loves them. I also have composite toe boots and I will say, I have dropped 200lbs of sand directly on my toe and had nothing happen (I didn't even feel it). They are a must-have for people who work around heavy stuff that might fall on their toes.
