So, finding out you have a large leg length discrepancy is challenging enough as it is, without having to lift industrial steel-toe boots, which many do not. Researching lift modification quite a bit, I discovered American Heelers. Not only were they personable, professional and reasonable- their work was clean/neat, finished and shipped on time & as discussed. The boots have held up to quite a bit, so after over a year of true boot wear, when it was time for a repair I decided not only to return to them for the repair, but to send out a second pair of shoes (high heels) to be lifted. I am thrilled with the work they do, how it is done, and what the lifts stand up to. I would recommend them to anyone, but even more so if you need solid soles you can count on. 10 out of 10 - with both orders!
