Lack of a stability in the middle foot but overall

I love these so far. I’ve ran in them and walked in them a couple of times each. As a woman, I ordered the men’s version, so that it’s less narrow. It’s perfect for me who normally goes for a wide shoe in women’s sizing. My speed is better during runs and when walking/running, I haven’t been wearing my knee braces at all. They’re great on my knees.
