You need three pairs of AE shoes to alternate (if this isn't actually true then this whole math may be wrong)

lets say you get 2 as seconds, one at full retail, thats roughly 700 dollars. let's also assume they are going to last ten years. They will each need a resole every 2 years just about, which means 5 resoles each (what AE says is the upper limit of recrafts they do), amounting to 15 resoles over ten years for all the shoes together. Each resole costs 125 now. 15 x 125 = 1875, 1875 + 700 = 2575 is your total investment for AE shoes over 10 years.

Now lets say a crap shoe at 100 bucks a piece is going to last 8 months. you will need 15 shoes over the course of ten years then, and then at an average of 100 (price of rockports at zappos), then you pay 1500 dollars over 10 years.

Our luxury shoe method costs over 1k more.

Not that I will ever stop buying nice shoes, but I would actually like to know for my own curiosity how long 3 pairs of AE shoes if worn every day can last, and if my math is right.

Anyway, food for thought. Sorry, its late at night.
