My first pair of these boots ended up coming apart at the seam and letting water in. After an email to the seller, they promptly addressed the issue, requested photos to forward to the production team, and sent me a new pair free of charge. My second pair was fine, although I felt some sort of pulling at the seam again (it felt/sounded like something unglued? It's hard to describe). But after wearing them for a while in the rain, mud and in my garden, I can safely say they are functional.

Overall, they're really cute, they work well and for a good price. If you have problems don't hesitate to send the seller feedback, they are very responsive and care about their products.
