I bought another style boot that was uncomfortable for me personally, as they were a bit heavy. I normally don't shop for boots online because I like to see how they feel first, but I figured with the 14 day trial at work to see if you like the boots, why not? So I went with the Marins for the exchange and I'm glad I did. These boots aren't too heavy and they're very comfortable to work in. So far they seem pretty warm and I'm working on a metal platform under a bridge, but it's only gotten into the upper 20s where I'm at. I bought the all black ones with the Brunt toe cap and I love this boot. We'll see how long they last me, but so far I'm really enjoying this boot and would purchase again
