Short for the Dr Martens.
Whilst doing my shoe research for the last couple of projects which were, well bases on shoes. I did a bit of research on the DM seeing as I own a pair. The first website I looked at was the DM website which has a very informative page about their history and how they were invented which is quite an interesting tail. http://store.drmartens.co.uk/t-history.aspx It also includes this video.
I also looked at how they were made and the different components which make them so darn comfy (after the 2 month wearing in period which can involve some pain). http://www.drmartensforlife.com/for-life-products/
Dr Martens are currently running a 'First and forever' campaign where you can talk about you first ever DM's which I must admit I think is a bit weird but here’s a video from their website promoting the campaign.
