This wireless charger eliminates that problem. I would not purchase again because of this. I cant get over how happy I am with this purchase! Have some old Doc Martins boots, they took me a month to wear in. -It has a very comfortable heel which makes the shoe comfortable and elegant. A couple of 10, 12 and 13 milers and two long 20 miler runs. The sizing is why I dropped a star. They did not make it four months. Basically everything you want in a slipper from the relaxing feel , warmth and roomy break from regular shoes, these ARE NOT. Individuals on the calls noticed a difference and said you sound so much more clear what did you do? It is portable so I can take it with me on the road.
