I agree with Muttley to be honest. I choose for comfort and personal fit. Its very nice to say you want to make sure your “purchases don't harm others” but in reality it’s a much larger job that that. Where is the sole manufactured, where do they get the rubber? What about the laces? The plastic for the lace ends.. the fabric for the shoe itself the material for the insole? Is it all manufactured by the company, where do they get their raw materials ?
Even this site and its magazine, right down to ink paper and staples. Do RW have a socially acceptable policy, where do they source their paper, where is it farmed and how are they treated. What about their advertising?? Jump up a level to the Magicalia Company. They host the site and provided this lovely colour scheme! Are they behaving responsibly, where are they based, what is there energy consumption like, where are they servers manufactured? What about your ISP? How about you computer? Where any components made in third world countries?? What did you eat today? Where did that originate? What are those company polices? Where did the ingrediants come from! What soap do you use etc etc
Frankly I could go on for pages in greater and greater detail. Yes it would be great to know my running shoes where not harming anyone else but my first concern I am afraid has to be are they harming me?
