This is the best lift I've owned.
This heel lift offers advantages over others I've owned. My clinic told me I have a 1/2 inch leg length discrepancy. They gave me a cork lift. I later found the cork lift was only 3/8 inch. I could only find 3/8 inch lifts. This comes in 1/2 inch. It's a sturdy product. The rubber doesn't "cave in" like the cork did. The lift is flat on the bottom and inclined upward from arch to heel. It fits nicely under the insole of my left shoe and stays in place. I noticed the comfort improvement immediately.
