All go bobbly. However I did really enjoy the extra cushion on the heel. Edit. These are stellar shoes. They dont rub, chafe,or slip, and they have a rubber sole not the padded kind that tends to get smelly and gross. As others have mentioned, the length is adjustable but the height is not. I FINALLY came to the realization that the bracket itself was too flat. But those dont ?shave? they trim hair. I always wait a full year before writing a review on footwear. The highest point was just under my bra line.
