Amazing does the job. I removed the tag on the sole and the design peeled off before even wearing them. They arrived in perfect condition. I like the top of the slipper sock, however the soles are cheap and have begun to crack and wear thin. There is no real arch support inside so if you get plantar fasciitis, make sure you have an insert that works well for you. the switching is made fast once you have set it up. Put air pump in basket with bike tools. I currently have K712 Pro and K240 from AKG. I purchased the red one! I also get sores on the backs of my feet still from these so I have to wear socks.
