These are great. I bought these because I was tired of my feet swimming in the regular construction-type boots during the summer. They are very comfortable and highly breathable. You sacrifice ankle stability for mobility, which for my summer work is just fine. The only gripe I have is that after hours of wear you feel it in your soles. Next year when it turns hot again, I'll probably be swapping out the inserts for something more substantial. Other than that, very happy with these boots.De excelente calidad y para trabajo muy buenosMade for arid environments. Do not buy if you deal with mud or moisture. Better yet, don’t even wear this boot outdoors. A good boot if you drive a hi-lo in a warehouse. Pretty worthless for anything outside where you’ll encounter filth or moisture.Overall nice boots lightweight and breathe well. Only problem is in a diesel shop they are already starting the fall apart. Maybe been a month since I got them. Honestly I am not surprised due to the amount of abuse they get. Just be warned they are definitely a light duty boot.These boots feel amazing, but after about 3 weeks working on ballast the soles are almost worn down to nothingHad these for less than a few days. The safety toe on the left foot rubbed on my pinky toe. The strangest thing is that my right foot is very slightly larger than my left, so it was obviously made just a bit off. I wish they had a better quality control before sending these out, but that's what I get for experimenting. Your success may very, just know that these are not equal in size or construction.Excellent wear,functional just like my old operator boots from the marine corps. They breath an water resistant. I did add a coat of repellent just to suffice my ocd.The boots are lightweight and comfortable as advertised, however the wear alarmingly fast. I currently work in a field position surveying, so I spend a lot of time on my feet walking on dirt, grass, concrete however these aren’t really heavy abuse. The soles are wearing quick and the front toe is starting to come loose after 3 weeks (06/27-07/11)Une de mes meilleures paires de bottes dommage qu'elle ne sont pas imperméable et tenez vous loin de l'eau de javel.Muy ligeras, cómodas y excelente diseño商品は良かったのですがスナップが取れていました。ので返金手続きしました。製品の検品が甘いのか…少し背伸びして初キーン購入でしたので残念です。
