Leather straps are soft too. The listing indicates that the wireless technology is 2. If you have hard feet they might be okay, but for soft feet like mine they are slow torture. No response from warranty and honestly no sure if they even exist anymore. I looked no further and ordered the first no frills pair that I saw. All the edges were badly scratched. It has only been washed once. It weighs a few pounds but isnt too heavy. Everything fit together well. Hopefully it holds up.
