I don’t suspect they’ll last if I wore them everyday but I wear them only once in a blue moon so they will definitely last me longer. It is the same size as the unit I had that didnt have a spot to charge AirPods and so far it is performing great. I have three pairs of the t strap thong sandals, and they last forever! Moved and lost my charger to my Beats Solo 3 and this charger was a perfect solution. Sole is stiff so a bit hard for them to walk but fine once they got used to them When I put the right shoe on a flat table, the right side of the heel is up off the table; if I press down on the heel so that it is flat on the table, the left side of the sole lifts off the table. ( there’s one that has exactly the same features but instead of laying your phone flat on a circular pad it’s a stand, look into that one if you’re interested in purchasing)Edit as of August 1st 2018Anker contacted me and sent out a replacement for the item and that replacement was having problems as well so they refunded me. I probably couldve gotten the 40 pairs its said to hold but I prefer keeping my shoes in their boxes, unfortunately not all of my shoe boxes have held up over the yrs but this worked great for those now boxless and let me get creative with storing a few pairs still in them on the shelves. _________________________________________________________________(Original Review) Now that Ive had the shoes for a while, I am starting to like them. I was so pleased with this dress I ordered the white one as well.
