I believe same thing happened to me. Got in around 7:05am pst and messed with captcha and trying to cart for 45 min. Size and captcha then just randomly disappeared
ADC Pairs came in. Super hyped that I was able to checkout after taking an L on o.g nmds somehow lol
Tried on my size 11 before I left and it feels a bit more loose compared to my worn 1x coppers
