Caveat emptor. I purchased a pair ($130- Super Walk) in Sep of 2014, found them to be uncomfortable due to inadequate support and cushioning (similar to shoes selling for $60). Other than the quality of the shoe, the fun began when I returned them per the guarantee of a refund in 30 days. It required a few calls and emails to learn that, after 45 days, my refund request was still 'being processed'. Inquiring about the CEO, Tim Wallace, finally got them to honor the refund guarantee. Much different experience than with Shoebuy or Zappo.
