I had a pair of tall pumps that I needed to wear for a wedding, but I was between sizes. I ordered the larger size and hoped that I could get inserts to make them fit. Originally I bought Petals for the heel but they did nothing to help. I peeled them off and tried these. With the entire piece in the heel, the shoes still slid off when I walked. I felt like my heel needed to be lower in the shoe in order for them to grip properly, so I cut off the part that touched the sole of my foot and placed it at the front of the shoe instead. (See photo for example…pardon my corgi’s feet in the background, haha!) It worked perfectly! The shoes now fit and don’t slide. I’d recommend this hack if your shoes are slightly big and your heels slide out when you walk. Aside from needing to do that, these are great. Very comfortable and squishy (but not so much so that they lose their shape). The material on the outside feels very nice, too – not luxurious exactly, but certainly not cheap. I feel good wearing them. ..More
