This is now July 1st, 2020, and, unfortunately, it stopped working a few days ago. However this is my third other GenY purchase and like the second it is a failure. Afortunadamente la compre cuando estuvo en oferta y pagué mucho menos que su precio de siempre. Crap shoes, coming apart everywhere. I was never able to use them before because the shape of those just never fit in my ears. Love this dress it feels soft and bouncy doesnt cling. They?re extremely comfortable. Range - Jlab has about 1/2 the range. I like everything about the shoe, except for the fact that after just one month of running about 15 miles per week, the outsole has already worn away at the outside edge of the heel. I have only been using it for a month or two so cant comment on longevity.
