Review on Premium Boys' Non-Slip Lightweight Toddler Slippers - Slip-On Shoes by Alex Montgomery

Bought for a preschool class where they ask for slipper slippers for kids that don't slip. I like that the bottom is waterproof and not slippery for him when walking. Unfortunately, the landing is very strange. They fit my son in length but for some reason there is a lot of room in the heel. It doesn't seem to bother him, but it looks silly and can be dangerous. Another downside is that the opening for his foot is unusually narrow for this shoe size. I could probably size down to fit the heel better, but then I wouldn't be able to fit my foot in. So right now the heel is bulging and I had to cut really small slits in the upper to make sure it doesn't mark his ankle. I would come back but I like that they are non slip and like traditional slippers. I just wish the proportions were better.
