and plan on buying one more pair to match up with a dress I bought on Amazon. Well actually I wanted the power, but someway my order got misunderstood, and I was sent the beet chewable. The heel height is comfortable, and provides good stability when waking on uneven surfaces like grass. Battery: 2 days easy. They also have memory foam which I do not like and never read that in the description. I ordered a mens size 13, my size in Womens is 11. First off, yes you can turn the LED lights on/off that are on the base. I will be returning this item. Quite the investment at such a great price. All I have to say is WOW!
