I recently had my left hip replaced and bought the sock/stocking aid. The operation was fine but I had not realized how long it would be before I would be able to do the simple things such as putting on my socks. My wife dutifully obliged but after several weeks I decided I needed to do something to relieve her of this chore. Having viewed your website I found the sock/stocking aid listed. I tried it out and was amazed how effective it was. My socks went on like magic. What seems such a simple device must have taken a lot of development to end up being so effective.
