One of the few sites listed to carry 4 percents is Eastbay, save the hassle and just wait for Nike or Dicks to get them in stock.. I ordered a pair only to find out their order system is bugged which sends the customer a confirmation but never confirms on their end, I called in after never getting anything for 2 weeks, waited 2.5 hours for a rep only to be hung up on by some confused Indian.. called back waited 2.5 more hours only to be told their system has been crashed for days which (they can’t even ring anything up on their end) . Worst customer service I have ever had to deal with... save yourself the trouble, if you do order good luck you better call and confirm your confirmation is legit or you will be waiting for weeks for no package.
(Also if you are in my boat, don’t send an email they never respond, due to their system being broken they never turn chat on either, you will have to just bite the bullet and wait on hold a few hours)
