Oofos are amazing. This has eliminated my lower back pain. I ordered a 3rd pair and the sizing is completely inconsistent. I always order my regular W8 and the black pair is HUGE! Its actually quite dangerous when I wear them because I trip over the extra sole at the front. I reached out to the company but they said they cant replace them because I bought them over a year ago. Since I had 2 other pairs, I wore those out before wearing the one that is too largeit was in storage. I emailed them pictures comparing the regular 8 with the incorrect 8 and they said there is nothing I could do. Im very disappointed by Oofos.
