I bought these shoes and liked the feel. However, within a month, many of the nubs broke off. I contacted Adidas for a return pair . They don't reimburse for return postage. No one from Adidas ever responded. Don't waste your money on these; buy another brand, or expect to find that they will deteriorate in short order.

As an update, I bought a pair of the men's version and they appear to be holding up much better. Like so many things, men's products are also made better. Additionally, I got a better price on them than the women's also.
