Thought over. These are not very comfortable at all and run about a half size too small. With this pack of multi sized hooks, I was able to hang my tools, bicycle, and extension cords. I read some negative things on these so was kind of leery about purchasing them but was pleasantly surprised. I purchased these on Aug. Theres no antenna tuning or engineering design in this at all. The stand seemed fairly rigid before I installed the shelves and after it was even more so. Pairing to my phone is easy and they connect automatically as soon as i pull them out of the case. NOT ANY MORE! The real star of the show however is the soles.
