Permalink settings

Let’s say my shopbase i called: shoes

Then I will do the following settings in WooCommerce 2.1.12 and WordPress 3.9.2:

1. WooCommerce -> Settings -> Products -> Product Archive / Shop Page = shoes
2. Permalink Settings -> Common Settings -> Postname = Checked
3. Permalink Settings -> Optional -> shoes
4. Product permalink base -> Custom Base = /shoes/%product_cat%
5. Shop Permalinks Base -> /shoes

Everything looks great but at the final product page I get a 404 error. Are my settings correct?
