I always get the size 7. It rinses off very easily with whatever temperature water you prefer. That alone is grade A customer service! I do have small ankles, but they dont slip there, and fit well. zThere is no beef in the metal to have it set firmly, and the glue and small nails do not hold the plate. And this was it. They are great for snow rain and even everyday winter wear. These pumas have an adjustable upper with a very soft underside for the comfort of the top of my feet. Obviously they get uncomfy after walking around for a while but they’re so cute it’s worth it! Thanks to all the reviewers who brought this fine, sleeper of a product to my attention.
