Bought as a spare pair but only used for one 5k. I can validate the purchase for authenticity if required - purchased direct from New Balance Nicely cushioned daily trainer but with a plastic plate for a bit of extra pop. Lots of good reviews online of these. Size wise I'd say these fit true to size, I'm usually a 9.5 in Nike and a 10 in Adidas for reference.
