6 months after purchase and these are ruined. Both boots have split open on the sides, where the top of the boot meets the band around the bottom. I tried unsuccessfully to repair with ShoeGoo but due to the nature of the damage, there's no way to repair and waterproof these. I will have to buy new boots, which I had hoped to not have to do especially this soon. I purchased her sister a pair also and those so far are fine.  My girls have gotten the same amount of wear time with these boots but for some reason, the larger size 11 did not hold up like the size 8 yellow ones I purchased. Very disappointed with this pair.
