This is where my review can really become subjective. I don?t know if pine sap caused the damage, or was this item painted and then assembled too soon? Not sure. but these were like cinderela slippersROCKDOVE has many other beautiful slippers on amazon and i tried a couple of others, all nice quality but fit and look just werent as i expected . Over all, I?d give it a meh. Caused blisters but I was able to adjust the heel strap by moving the plastic circle from the inside of the shoe into the next layer where it wouldn?t come into contact with the skin (see photo). On every other keyboard Ive ever used, this means ghosting. I saw this Sony and had high hopes. On a positive, my kid loves it and loves going on rides with me! Like, im in the middle of a 15 mins match, and I know after the game I will be charging. The story line is such a refreshing change of subject matter and with its twists and turns, was a delight to read.
