TL;DR You can choose how many socks you want to receive in your sock subscription box each month.
We have made our sock subscription as modular as possible. We want you, the subscribers, to customize your sock of the month club experience. That is why, when signing up for your subscription, you have the option to choose how many socks you want to receive each month.
You can choose to receive 1 or 2 pairs of socks each month. It is generally more economical (and let's face it, more fun) to receive 2 pairs a month.
