Occasionally I run across a great bargain on running shoes when a new year's model/update comes in, and last year's model is discounted to clear out inventory. (Sometimes they even have 'new' [unused, unsold] shoes from 2 years ago, HEAVILY discounted.)
There are certain Asics lines that my feet just adore, and have been great for me in the past.... but I wonder if the materials degrade / deteriorate at all (or noticeably) simply from age. So far, I cannot detect any difference.
Anyone know? Or have anecdotal experience one way or the other?
