These new MJs dont do that and they are perfect for driving. Once you have the actual suction cup (not the plastic case) flat against your wall, pull the lever down -- you will feel tension if you are applying the cup correctly. Now I know what my teenager daughter is getting for her birthday that is included to support the BearX headphones. From my perspective, if you like the looks of these shoes, it is worth trying them, but make sure you buy from a seller with a generous return period in case you get a pair like those displayed in the other reviews. Sound quality is not the top but considering the price, it is excellent. My daughter loves her new flip flops. Recommended That joy and laughter was worth the price! They were pretty stiff and uncomfortable for 4-5 days but I try to wear them as often as I can and they now hug my feet perfectly.
