Rarely am I super impressed with an online purchase bu these things are great! And for $21, they’re a steal! They’re perfect for backyard excursions and even look good. I’m a US 11.5D and the 11 is a perfect fit. Easy to slip into and, with the little heel ridge, they stay on - even on a grassy slope. I’m guessing they’ll only last a few seasons before the soft sole wears through but that’s OK. These are comfortable and perfectly suited to their role as back-door go-tos.
