Lack of “back” button renders almost unusable

The app does not have a “back” feature that returns to the previous window (ie applying any search terms or selected options). Say you want to look at boots that all have a certain sole; you search for that sole, then pick a boot to look at. If you want to go back to the list of boots with that sole, the only way to do it is to go to the specs of that boot, and choose the sole again there. This doesn’t allow you to look at more than one search result without re-entering the search each time. This is a great app but the lack of a “back” feature makes it almost too hard to use.
