Remus's answer is good. I would add to that that Google has their first link filter. If you have two links pointing from page A to page B, Google only passes link authority (pagerank) and reputation (keywords in the anchor text and relevant surrounding text) through the first link that appears in the code. The second link does not pass anything. So, whatever the anchor text of the first link in the code is, that's the anchor text Google is going to use (Remus is right that anchor text has become less important).
The second link does, however, dilute the amount of pagerank passed. So, like Remus pointed out, each link in your scenario only passes 20% of the pagerank. Since Google ignores the second link to the shoe page, that 20% of pagerank does not get passed. I'm not sure if it stays on the page or just gets lost.
So, what does this all mean? From an SEO standpoint, you want the link with the targeted keyword to be first in the code if you have more than one link to a page. Also, you don't really want to have two links to the same page on that one page. Now, that's from an SEO perspective. From a user perspective, it may make perfect sense to have that second link and the page may convert better. So, you'd just have to decide which is more important...and it's probably the user perspective that's more important.
