Adidas Shoes
Note: Sambas and Yeezys fit different! We recommend for you to wear your Sambas true-to-size, whereas Yeezys can be a bit different from the regular pair of sneakers.

Yeezy Boost 350 v2/v1: Go up at least half a size. For example, if you are usually a US10 Men's, wear a US10.5 or US11 Men's depending on whether you have a wide foot or not. If your feet are wider, it is recommended to go a whole size up.

Yeezy Slide: These fit tight! It is recommended to go up a full size as Yeezy Slides don't come in half-sizes. For example, if you are a US10 Men's, wear a US11 Men's for a comfortable fit.
