The shoes fit well. They are very comfortable. I have trouble with a wide ball of the foot and narrow heels. Most shoe's heels also are too tall, and sometimes the collars hit my ankle bones. I can wear these all day for exercising, walking around, sight-seeing, etc. The white mesh is crossed by clear bands. These areas turn yellow immediately. I've cleaned them each time I've worn them, and they're yellowed again within an hour of putting them on, even with white cotton socks. I've tried using enzymes, oxygen bleach, everything. If they just got dull from wear, I'd be happy with them. I really can't go anywhere in discolored shoes, so they'll be used for staying at home or walking the dogs or short jogs.
