Large - Men 9-1/2 up, Women 10-1/2 up (70mm, 2-3/4'' wide)

I recently had major back surgery to correct a severe curvature of the spine, the result of being hit by a car more than 50 years ago. Thankfully, the surgery was a success, and reduced a huge amount of my pain.One thing the surgery did not correct was that my accident had also resulted in one leg being 1/2 inch shorter than the other which caused me to have pain in my hip from walking after the surgery.I had the idea of adjusting an orthotic I was already wearing; but after looking online I saw this adjustable lift and thought “this is just the ticket”. It was, and it works magnificently!I wear a size 12W shoe and bought the large size. It fits well and doesn’t move around. I suspect I will buy another one of these as a back-up. I highly recommend this product.By the way, my hip stopped hurting once I started using this lift. Perhaps if I’d put these in my shoes in 1949 I wouldn’t have needed the back surgery!Note:On Aug 24, 2015 my surgeon look at my lift and loved it he showed me a little imbalance in hip height from x-ray took off two layers of the lift and hips are balanced.

After a hip operation, I ended up needing a lift for the unoperated leg/foot. This is a great product, it allows you to peel off layers (or add ones back on) until you determine what makes you feel level/balanced again. For shoes, sneakers & bedroom slippers that don't have a removable inner sole I recommend get a light inner sole (like Dr Scholl's type) & place that over these plastic lifts. I got both the medium & large. As I am a woman, wearing size 8 1/2, the medium works well in typical shoes but for wider items like boots that may have a wider heel area I also purchased the large. If you get a few pair then they can stay in those shoes vs. always having to pull out the one set you own moving them in & out from shoe to shoe. Worth the price, so far see no sign of wear. They stay in place well when placed under a removable inner sole. I am so happy with this item!!

I have a slightly longer right leg so I put a few layers of the heel lift into my left shoe and it seems to have helped. I was having some hip pain from the leg length difference while running. I run 30+ miles a week so any bio-physical issues will show up with that amount of training. I read that you shouldn't use a heel lift and try to correct your stride etc. Well I do land mid-foot and I'm not a heel striker, but the subtle lift does make a difference. My running has improved and I rarely have hip pain now. Granted my problem was minor, it worked great. I only wish you didn't have to order a huge heel lift, because I only used about 1/10th of what was provided. Would be nice to offer cheaper options, maybe half the height and material of this same type of heel lift. Holds up well overall.

Best heal lift i have found yet for leg length issue. A small piece of two sided tape holds it in place.

As I just spent the last 2 years walking a pair of these off, to the point of destruction, I feel competent to give a fair minded review. First, they do work...They more than make up for the shortness in one leg that I have to contend with. Second, they are well made and tough. Forget those spongy lifts that will feel great at first but compress over time. I need firm support to avoid stressing my Left hip by compensating for my shortened leg when walking. These put me on an even keel with every stride and eliminates my hip pain completely.I'm agnostic on the benefits of these lifts being adjustable. Personally, I'd much rather have a solid one piece support that comes in the 3/8 to 5/8 inch (ideal) size that I need. Perhaps they should expand their line of products by offering solid lifts in a variety of sizes.The problem with these multi-layer adjustable supports is the layers can start to shift by themselves over time. It may take a while but it will eventually happen. It does make me wonder if I wouldn't be better off planing a piece of hard wood or plastic to achieve the same end for a lifetime lift that would never wear out. And a solid lift would be much easier to clean between shoes.A solid lift would also minimize the mold that tends to form between the layers after months and months of being exposed to your living, breathing and sweating feet all day. Even placed under a foot pad, these lifts will eventually funk up on you. And if, like me, you care to remove them for use in other shoes, these multiple layers will start to loose their natural adhesion and tackiness. Which is another reason they'll start shifting on you over time.Hence, my rather mediocre rating. Yes, they do work. They feel great when new. And they gave me 2 years of faithful service before giving out.Maybe expecting a lifetime of service is asking too much. But it wouldn't be a great chore for this company to fuse these layers into a solid form and they jolly well would last a lifetime. Or a decade or more.. I'd pay extra for that kind of dependability. And of course, the sheer utility of being able to use them in a variety of shoes in my closet in a pinch would be a great improvement.
