I just received my T75 and H75 inserts. I bought them to relieve my hip pain and improve my experience in heels, respectively. Time will tell with the hip pain, but when I used my H75 in high heels I noticed an immediate difference. My ankles were stable and my weight shifted more to my heels, relieving my toes. It was almost like wearing tennis shoes. Maybe not quite that comfortable, but still, it was the improvement I hoped for. Now I can finally wear and actually walk in heels without pain! I am also happy with the customer service, the fact I got a free upgrade to expedited shipping for buying two inserts, and the point system to get discounts on future purchases.
