Very rare to find fakes in these kind of pairs, I have not heard or seen any with regard to the 252.1 pack. Would be little risk to getting these newer pairs without it being a fake.
Your gonna have to check Instagram for some collectors who still have these og models and keep checking eBay although it’s rare occasional they pop up. Should be the best place to get some track of them
Agree man the 3.1 easily better looking shoe, should be the easier of the two as most will for for the 3 first, would of been better he dropped them today always easier when ASICS drops with clothes.
