I tried several brands: Stride Rite, Minnetonka, etc. I would highly recommend getting these with the Mix Pro amp as it makes volume adjustment that much easier. Has a vanilla smell. As a former Red Wing Shoe Manager I would of thought for the price I was going to get an exceptional pair of flip flops to wear on Vacation. I was extremely disappointed in the quality of these slippers & would not recommend buying them. Theyve only gotten worse, and Im embarrassed to put them on her, and unhappy that I spent what I did for them. I enquired of a couple of shoe repairers about resoling with harder wearing material, but the prices were comparable to a new pair of quality leather sandals, and since the non standard repair might not have been successful, I have given up on them and bought a pair of all leather Josef Seibels for £7 less than such a repair would have cost me. I bought 4 shelves AND I COULD NOT BE HAPPIER. Only thing that seems to be off is the thickness of the lenses, they are a lot thinner than the originals, but it doesn’t affect the fit. With the adapter being so small, I dont have to worry about losing it.
