These insoles are the best I've used for hiking. They made an immediate difference with no "break-in" time. Excellent arch support and completely eliminated my foot pain over 5+ mile hikes.
I had heel spurs and was facing surgery when a friend recommended I try this product. Immediately I could put my weight on my heels again without the extreme pain that I had for months. Within 6 months of wearing them every day, I could start wearing some of my "normal" shoes that wouldn't allow for inserts. I still use these when I will be on my feet all day (I am a teacher).
The only thing that I don't like is that I can't wear them with my sandals and some of my other shoes.
I highly recommend anyone with foot problems to try these!
