I usually love New Balance and have never had a problem with their shoes until now. The shoes were great for about 5 days, but the area near the toe is all mesh. I thought that would be great for letting air in, however they formed a hole in the toe on my right foot after maybe 5 uses. The left shoe soon followed suit and now both shoes have a hole where my big toe hits.I don't have Godzilla toenails so I'm not sure why they would wear out so soon and you can see my sock through them. Very disappointing.
