Sole Society: Earn Free Shoes just by inviting your friends to join!
Sole Society is a shoe club, where every month they will give you a show room of five shoes based on your style which they determine by the style test you took when you joined. Shipping is always free, and returns are hassle free. If you can't purchase that month just choose to skip it, no obligations! They will not charge you if you forget to click skip a month. They only charge you when you, yourself makes the purchase. If you don't like the selection of shoes, you could also choose to get five new pairs in your shoe room (Your Closet). The shoes are $49.99 with free shipping!
Now for the good part: For every 3 friends you invite to join, and they all purchase a pair of shoes you in return get a pair for FREE! This is great, it's definitely worth trying.
