In my search for some ethical, sweatshop free trainers I stumbled across the following webpages which I think are very useful and wanted to share. :)
This page highlights the issues around shopping ethically in a really nice way: http://www.ethical.org.au/get-informed/issues/
And this page highlights five key principles in shopping ethically: http://www.ethical.org.au/get-informed/5-principles/
P.s. It turns out you can get ethical, sweatshop free trainers but at a cost (obviously). Most websites I found started at £50 for a pair of trainers, with some costing over £100. I know some people pay this much for shoes anyway but I never have! Whilst I would love to buy these (they were nice shoes!) I need student prices. So I opted for some trainers I found on the Oxfam online shop (http://www.oxfam.org.uk/shop/).
It turns out a lot of charities also sell on Ebay. You can search ebay sellers by charity type depending on which charities you personally want to support: http://pages.ebay.co.uk/ebayforcharity/
Our souls are not hungry for fame, comfort, wealth, or power. Those rewards create almost as many problems as they solve. Our souls are hungry for meaning, for the sense that we have figured out how to live so that our lives matter so the world will be at least be a little bit different for our having passed through it.Rabbi Harold Kushner (via thatkindofwoman)
