Several Reasons:
1. No one is interested in the stuff you are selling. (are you only selling shoes? . Your landing page only has shoes).
2. Perhaps your price point is higher
2. Get a professional 'paid' hosting - Not a free weebly subdomain.
3. Arrange products in logical order with high quality images.
4. Get rid of th0se annoying pop-ups and I believe you have two of the. So a before a visitor gets to see your product they have to click twice to get rid of them. You can think about pop ups once you have some customer base.
5. You are selling to people in art - they are more visual type. They like to see artsy presentation. Your website is very simplistic.
ask yourself, would you buy stuff from your website?
