Im so glad I bought these! I was VERY DISAPPOINTED when I started wearing this bracelet ! In conclusion, I understand why some people would want to return these after putting them on and hearing the sound for the first time. 5 10 (US)You can see on the pictures how it fits. Which might have been made worse due to it not fitting in my ears well. My last Slim were so much better without the problem. Just what I was trying to find- a warm camp/backpacking shoe, but I?ll be wearing all winter too! When I finally got these, my feet began improving immediately. Good product as expected We had 2 sets of holes that just ripped right out before my husband went and got his own anchors, which worked like a charm on the first try.
