Well it has been 3 months but there is still no sings of it on the first pair. I have a 75lb double kayak, and the bars are ok with the weight. The only reason I gave it less that five stars on durability is the part that the key ring attaches to is rubber not metal or plastic. Im currently searching for a reason behind this mystery. In the photos I wore hose on the left leg only so you could see how the shoe looks both ways. Very convenient, simple, and pleasant to look at. Its now been a few snow storms and as well as to/from school every day and they are holding up well. Trying to disconnect & reconnect by turning off/on bluetooth on my phone doesnt help. But completely unjustified in my opinion. One tap plays/pauses, while two taps on the right skips to the next song, and two taps on the left goes back one song.
