I switched to these because THEY DO NOT HAVE THE TERRIBLE MEMORY FOAM. I like the jack because I dont have to worry about them loosing battery life. If youve ever spliced electrical connectors before you should be fine. I’m out all day walking for work so I need a lightweight snow boot. However, this adapter runs at 20w opposed to the regular one that runs at 5w. Despite some negative reviews due to the cloth shelves (you were expecting a full metal 10 shelf unit for under $25???), this unit does exactly what it was designed to do, and it does it well. I usually wear a wide width 8. I was also impressed by how great they work, and for the price I paid! The shoe otherwise is beautiful and fits as expected. So I have to unpair the phone and then pair the watch.
