Its good enough for a couple of days work without having to rely on finding plug sockets to charge them! So anyways fast forward to today. I will definitely be getting these in the future. First, there us an obvious seam on the upper leg. I am pregnant with SI joint pain so a good comfort shoe is a must when Im on my feet running around with my little ones. Buy two sizes up and even than you may not be able to wear socks. Having five bikes, Im always moving them around the house to store some away in the basement for the winter and bring some to the first floor for seasonal use. 7 fixed it. The only thing I didnt like is the connector design. They do get dirty pretty easily if you take them outside, but are super easy to throw in the wash and can go in the dryer without any damage.
