I'm a size 4.5-5 and saw that you should size up in Sleeks so ordered a 5.5. They were too small so exchanged for a 6. Not sure if they're too small - I think they'd be ok if they give a bit but not sure if I should order a 6.5 or if they'll be too big. Seems crazy! I really like adidas but find their sizing a nightmare.
Does anyone have any advice on sizing or if they give at all with wearing?
