Go 1/2 size up if you can. These look identical to Nike Tanjun's and are very close to the same quality. The sole material is not as flexible but the uppers look and feel identical. These shoes look great and are incredibly light. Ordering another pair in black.

That being said i would not recommend these as running shoes. These are very nice for walking shoes and everyday wear but I would never try to run int hem. The sole does not feel like it would do as well as dedicated runners from named brands and it is a little slick.
