Have played in my work shoes always look for already 20 minutes, get imense low back pain, which lasted for days. Until my work colleague had reported these insoles.
I myself have not had a heel spur, but only low back pain.
Inserted the soles and since then no more back problems. And it runs up really easily.
Am so excited that I ordered a second pair and was in my leisure shoes.
Through the soles, one is also a bit higher in the shoes, so many shoes not whet the ankle and I get no more bubbles.
This product has its 5 star fully deserves.
