Flux footwear, if you haven’t heard of this brand you can look them up. They sounded good to me, but they didn’t work well out for me. If you’re curious to try this would be a good way. They weren’t cheap. They advertise that they can be worn barefoot, they gave me blisters. My heels ran holes through the back as shown in photo. Otherwise really good condition. Others seem to like them a lot, they just aren’t for me. Size 7.5 per their size chart Soft pink color “Massaging insoles”
