Acu-Reflex Massaging Flip Flops Women's

I bought the exact product before. So I’m buying it again to improve circulation in my feet. When I first started wearing the original ones they hurt my feet and I could not wear them long. Later, I could wear them anywhere. But I bought the new ones because overtime the massage texture of it dulls because they’ve been overused so I bought new ones. Plan to buy another pair later.
