Personally, I think they are a touch too small, and that an extra 1/2 size would have been better. Didnt even last the one day trip to my home. Funny thing, no matter what I do to adjust the fit it wont read the heart rate. These socks are easily a decade old! Recomendo o produto e o vendedor! My package came very quickly. Got these for my elderly father and boy, does he rock them! In fact, Im just sitting in my house, wearing them, because they are THAT comfortable, especially with my hard tile floors. I have a MTB and I was only able to install because I still had all the rings, I just moved one to below the handlebar mount and it worked perfectly. These would be great for travel because you can wear with a dress or shorts.
