Got them for my fiance, due to the other brand of steel toe was very uncomfortable. He wore them all day shopping with me and never complained once! Best buy ever!

Real good work boot. Sturdy and comfortable enough. 40-60hrs/week in AMXL warehouse and they hold up good. Switched out insoles and laces 6 months in. Going 13 months strong in these. Minimal wear for the time. High quality from Caterpillar as expected.

Love the style, I stand/walk for 10.5hrs 4 days a week in these. The first week they weren't super comfortable, but thats likely because they needed to be broken in. The steel plate did rub my toes uncomfortably, but a thicker pair of socks fixed that easily. Nothing super thick, as a reference I generally wear those extra thin footies/no show socks. So something just a tad more padded than those. I did eventually purchase a cheap $10 insole as over time the original just wasn't comfortable enough. But these are my most comfortable pair of work shoes currently.

I really like these 'boots'. I would give 5 stars if they were a mid-top... -They hit me right below the ankle and that hurt till it broke in. They were lighter than I expected. They got great cushioning. I put inserts and arch supports in all my shoes still tho, cuz it can always be better. I have wide feet, I bought these a full size bigger than my sneakers. 4stars. I wish there was a mid-top version.

These shoes are quite heavy, so they are very uncomfortable. Although the look and style are okay, I will not recommend them at all.

Shoes are way too big and it hurts my feet. The steel toe can be felt and it hurts my toes. No comfortable at all.
