Una perdida de tiempo. And I guess the one cannot exist without the other. I love this as it keeps everything organized and together. I was so excited to use this exercise bike and I received the product on time. I was able to remove a jellybean sized clump of wax from my ear. these are great athletic capris but you may end up frustrated with getting the size right. why not? The price is fair, and its honestly quite practical. The no return policy says it all. They are a tad big in the toe, but the heel secures nicely and I am not slipping out of them. Going back to purchase the olive colour!
