Easily split/tear, but they work well until then
My heels are very brittle and crack super easily, leaving me in pain anytime I put any weight on them. So I bought these to try to bring some cushion to my heels to let them heal (no pun intended) properly. I used my first one and within a few hours it split down the front (see pic). I wear flats a half a size too big so it wasnt rubbing against anything, and there was no reason it should've split like that. I thought I had just gotten a defective one so the next day I put on a new one. Within 4 hours, that one split down the same seam, right in the middle. I put on my third one and it is holding up a little better now after 5 hours, but hopefully it will last the day. That being said, it has helped with my heel pain. If they would drop the price a bit, I would regularly buy these as one-use heel inserts because until they split and fall off, they do work pretty well.
