As for me, a heel spur was found, my doctor put me on such a pillow. In Sanitätshaus I had to pay with prescription 10. Deposits from there I find very pleasant. In order not always to fumble from the Gassi shoes in the "Outgoing" shoes, I ordered here Eratzpaar and am happy with it. The Pedag heel cushions are a bit softer than the prescribed pillow, but comfortable to wear and priced well recommended.
