Not too shabby over all
Bought these for going to my husbands baseball games. There’s enough heat to keep the chill out and my feet feeling comfortable in my mesh topped sneakers. These would probably feel warmer if I had better insulated shoes and I would feel more warmth if my socks weren’t so thick. Easy to cut down to size and clearly marked cutting lines. I don’t plan to be walking around too much except to a rest room with them so durability is not a concern of mine. Over all a handy thing to keep in my sports tote with a charger.<br /><br />Other reviewers disappointed with them not holding heat, the product description (although the headline could be worded much better) clearly states they won’t retain a charge and must be plugged in to warm you. I knew full well what I was buying and am not surprised by this at all.
