Here?s a couple of observations. I am now using the microfiber cloths from my reading glasses and it does a better job. I know its from DROP but still for this price (470$ after tax) i kinda expect a little more in the accessories department because you can bring this everywhere not with a 3 meter cable. Cushioned landings. They seem to run a bit large. I almost think they farm out their manufacturing to various countries thus the sizing inconsistency. Perfetta e comoda calza benissimoGrazie So I exchanged them and they worked great for a few months. Right now its between 72 to 81 degrees here and I dont have an issue with feet sweating when I wear them out. First pair: the colour didnt even match; one pair was stark white, the other beige/off white, with one strap twisted so badly the edge of the strap pressed into the top of the foot.
