These are my favorite sneakers for any heavy walking, shopping and working out. They are breathable, memory foam. I love them! I wear them a lot. As I'm getting them off, I notice they do smell, even my socks do too. My feet are sore I give them a good rub but more so, they itch and I wonder if I've caught athletes foot again. Maybe spread from one shoe to another. I smell them, smell my socks, itching at my toes and bottoms of my feet. I use my sock between my toes too.
