Before buying these I read thru all the reviews of ppl saying they run a size or half a size bigger. So I purchased a 7.5. I'm a 8.5 in shoes normally, these 7.5 fit perfect. I'm glad I listen to all the reviews and went a whole size down.  Thank you reviews!!!! The warning is correct. If you order your regular size they will be too big,  size down.  I freaking love my green new , in a adaias box shoes. I purchased my shoes thru SneakersRx!!!
