Well i got these thinking they would be better then the $70 ones i purchased at a P/X in my location and boy i was wrong these are no better then the cheap glasses at walmart in fact the ones at walmart are better cause at least the lens dont fall out they are by far the worst glasses i have ever purchased and will not buy from here again.now i will say the guy called me and he swore up and down that they are real nike glasses but i know nike dont make cheap stuff so i doubt these are i think they are a knock off that he got for cheap and is selling on here but just know that they will not make you happy when you get them in the mail and see for yourself how cheap they are well i hope this helps you all.
