Foam RNNR truly is ahead of its time. Easily the most comfortable shoe I've ever worn, and Sands Made In USA. Definitely an eye catcher, have gotten plenty of compliments on the RNNR out in the wild, and because of the comfort at this point it's pretty much the only shoe I want to wear. Need to take it for a spin at the gym on a non-leg day. Really gets to highlight the sox as well, bought a tye-dye kit and did a couple of pairs on my own a couple of weeks ago, but need to figure out how to make the colors more vibrant on my next few attempts. Still have four pairs left of the crews to experiment with.
