Have you bought Plae brand shoes for your child?

I already bought my 4 year old son (Skechers) a pair for pre-k but I'm not thrilled with them and these are supposed to be very comfortable and good for their feet. They are a bit pricey though, especially when little feet grow so fast, which is why I want to know if they're worth the $$. Anyone? You can also buy interchangeable tabs which is kind of fun: Plae Shoes
