I've had these shoes for a little over a month, put in over 60 miles on them -- and the tread is already worn down! Shameful. Another huge issue, well, the tight toe box. I've had to stop mid run and actually double check, making sure my sock had not slipped down. I wouldn't buy another pair of Hoka's if they go on sale for half the price. Quality control does not seem to be a major aim for this company.
