After being plugged into the chargers all night, we started to notice our phones were not keeping a charge throughout the day. During our cold Chicago winters, I wear slippers every day. The sound quality is surprisingly very nice. There was no way I would be able to wear these for five minutes let alone all day. That said, having ordered a half size up, the shoe fits well. I figured it was worth it to try them out. Liquid IV has made such a difference for him. For me, this level of kludge to overcome a design flaw, was not something I was willing to live with. But for me, they work perfectly. Got them, with slight modification they work.
