Adidas ADVANCOURT BASE 2.0 U. Simple and stylish black sneakers. - Brand: adidas - Color: Black - Size: 27.5 - Style: Sneakers Only tried on indoors. They didn't fit, and I couldn't return or exchange them because the time limit had passed. The manufacturer's size is 27.5, but I think they would fit someone who usually wears a 26.5 or 27.0. I ended up repurchasing them in 28.5.
