Came across this one on Amazon and decided to buy it and Im glad I did. You can get better quality ones for same price. It would have definitely gotten 5 stars if the replacement filters were not ridiculously expensive. I highly recommend NOT to purchase these awful slippers They are not even worthy of the 1 rating I gave them Size is just right for entryway. I had them the following day delivered to my door by a very friendly young man. Very good 👍 In any case, its almost a good mental trick for your lifts that your wrists feel so immobile and locked in. I wore yesterday to run errands and a teenager complimented me on the shoes! There is a punched indentation on the inside plus the screw hole that’s plenty large because of it’s shape, and if you put the bullet nuts on this area, some of the nut won’t have a surface to tighten to.
