These shoe shapers are excellent value for money. I have several pairs of knee-high and over the knee riding boots and these really help keep the shape of the foot like nothing else Ive used. I tried stuff in socks and towels into the foot section of my boots and it never works to keep the shape like these have. Highly recommend it and will buy a few more sets of these for the rest of my boots. I recommend everybody by these as they will add years to your shoes and keep a wonderful shape in them
