When I'm looking for shoes I filter the results by size.

Every time I come back on the website I have to re-filter by size even though I am logged in every time I visit the website.

I find myself filtering by size even during the same session, by switching from page to page.

It would be great if you store the shoes size I always look for, and make it visually very clear so that I can manually override it (if I am looking for someone else's shoes, perhaps).
