Running shoes: For non dedicated runners (under 100 miles a month) get two pairs of inexpensive, lightweight, that are sized correctly, and feel good.(always put on both shoes and walk around, there are no prizes for speed buying, but there are penalties). Two pairs are for alternating. It's only my opinion, but most people don't need hardcore expensive shoes.  Just like most people don't need a 5k carbon/titanium bike that weighs less than a pair of jeans.
