The included screws are pretty flimsy and will break without a pre-drilled hole. 4 stars only because the photo is deceptive. Had to order half size larger and wide width. I have used this product on dry skin, wet skin, with shaving cream/conditioner, with baby powder, pulling skin taut, slowly and at very angle possible but I did not receive the results expected. Very cute, but not white as advertised. I?ve gotten so many compliments on my pair. I would recommend for anyone with issues or frequent foot pain. It was a tiny area that just bubbled a bit where the shoe flexed when I walked. The pre-drilled holes do not line up, the holes for the dowels are too deep to be effective, the screws provided are far, FAR too large and will split the wood 9 times out of 10. The sound quality is great, with a nice base and surround sound.
