My feet havent ached once nor have ever been cold or wet even during walks through almost ankle-deep puddles and slushy snow. Need to buy the rest of required equipment separetly. Handlebars have a built in tablet/phone holder. It was not working properly but after charging for long time its working good . As a quick review the product hasnt disappointed me yet (1 week use). It has almost no resistance, so when adjusting the headphones on your head its easy to hit the volume slider and move it up or down by mistake. You can not even register them for the warranty as each time you enter the serial number and product number it says invalid What I like: the style is superb. But I would not call them "slippers" at all. I?ll be updating my review again to less positive if the other 2 stop working.
