5M since that second pair of boots was too tight. The fit on these sandals is perfect and they are extremely comfortable. Very little bass. These Cobb Hill sandals are as stylish as the Ecco but are way more comfortable. This would mean that I would be without my precious headphones for at least two weeks. However, I have two points of contention with the shoe which is why I removed one star. I will definitely wear this for a long time. Feels durable/ well built. I honestly never thought I would run into something like this but randomly after days of searching, I found these. I have a 2 tiered quality chain belt but it’s heavy and annoying when I want to wear it high waisted.
