coso182I went out and compared sizing when I found out about this drop. Not with Terrex, as I can't get them out here, but with their normal running shoes.
Adidas runs half a size smaller than other brands I am used to- New Balance, 5.10, La Sportiva, Asolo, Trezeta. I am 8.5 in these brands. In Adidas, chose a size 9.
