I've had 4 shoes modified from this company and each time they have done an exceptional job! I have a half an inch leg length difference, but it has been enough to cause joint pain in my hips, knees, and ankles in the past. Since I've had my shoes modified, all of my pain is gone! These shoes are also very durable and the insert is not noticeable at all (I have to actually point it out to others so they can see it). I'm so happy to have found this company and am for sure going to order from them again!
