The last time I bought shoes I bought two pair, both the same brand and model, only difference was 1 was greenish the other one was a redish color on the N and outlines of some areas. When I get to work the first thing I do is go into the office and change into my shoes (I leave a pair at work) After my day is done I go back into the office and swap my work shoes out for my outside of work shoes. once again both shoes are the same brand/models so one pair gets worn 7 days a week. mon-fri to and from work, then on the weekends everywhere. the other pair gets worn only at work and never outside of work. on mon-fri. Index of /twoshoes check out the pictures of the poor work shoes =( keep in mind these shoes are only around 4-5 months old. Just tonight I retired them =( Im showing you pictures of my work shoes VS the everyday outside of work shoes. I wish I knew how many miles I put on my feet a day. BTW I only retired them becuase they started to make noise when I walked. =( I was hoping for another month or two lol. and FYI I do replace the insoles midway thru the shoe life so they at least feel some what ok on the feet. and another thing, with out a doubt the best show I've ever owned was new balance. I've had issues with nike, adidas, and saucony, I've even had shoes come apart within 1 month of buying them. I think Im on my 6 or 7th pair of new balance 470/471 shoes.
