I was looking forward to receiving this shoe horn since it was adjustable. When I received it I was able to adjust it to a perfect length, but the shoe horn itself was made very narrow with fairly high ridges which tended to dig into the back of the heel. This made it very uncomfortable to use and was causing unnecessary irritation to the lower back of the heel. Even if there was some give, like in the spring shoe horns, it would not alleviate this problem. Stupid design flaw which could be easily rectified. Needless to say, I am returning it asap. Fortunately, I bought it through Amazon which makes returns simple.
