They wear out too soon, which is a real shame
I bought these for my job, working at an all outside dog daycare. These shoes were amazing with the wet grass (gortex type shoes can't manage long stints in wet grass) and great for puddles without issue. Most importantly, they didn't make me have unbearable feet sweat. Now, you still get some but for a 100% waterproof shoe? Way less than anything else I've ever tried. With other waterproof shoes, I'd be wringing out my socks anyway, but with sweat! They're also very comfortable and secure on the foot, I only ever had one instance with super sticky mud where it came off. However, after only 3 months, mine split at the connection between the sole and upper, meaning the waterproofing was totally gone. I was issued a pair of replacements (thank you!) but those too failed in the exact same way about 3 months later. Now, I will admit that I wore these shoes *hard* with 3 days a week of 12 hour days 100% on my feet in a lot of outside conditions and they were also my primary shoe for walking my own dogs. My guess is if you wear these less often than I did they'd last longer, but imo it's a design issue that needs to be solved. I really, really, really wanted to love these shoes and I'm having a really hard time finding a good replacement, but I can't afford to buy these every 3 months. Please muck! Fix that issue and you'll have a lifelong customer who will sing the absolute praises of this shoe.
