It was SOO irritating and gave me another reason to stop every 2 feet and adjust my shoe again. I plan to use these for my daily 4. It isn?t, but I fixed that using two nails. They look super cute and match her Scooby Doo pajamas. These things get beat up, it needs to be better than that. After a month of light use the velcro strap wore off making the slippers practically useless. Wow, I can?t believe how great this works ! Will update in a couple of weeks regarding performance! 00 ones. I?m still annoyed w the size, and not in love show they actually look on me, I wear them a TON and they are comfortable.
