The material does not seem very good quality but it will be a matter of using them and over time evaluating them. Socks are simple and each comes in an individual plastic bag. As soon as shipping takes less than expected, almost 4 weeks, it was very fast the only downside is that with the shipping of standard shipment, for Mexico it is not delivered by sepomex it is by another particular. Another detail is that it does not have an extra fabric indicating the talon as in other socks.
