As you may have noticed, there are Amazon.com ads on the site, and right here there is a blatant plug for their shoe division endless.com. They are having a sale on running shoes (among other things) and shopping there (or at Amazon.com) supports the site, helping to defray the cost of hosting all this super info. They have free shipping too, so if you are in the market for some new running shoes consider starting here. If there is a book you are looking into getting from Amazon.com, start here too. Thanks!
