+1 for the Nike Air Force 1, very comfy although I don't actually run in them. Own a pair in black and they look like business shoes from a distance haha
Also a big fan of Converse Allstars, but finding them in US12 has forced me to resort to online stores and ebay.
Anyone owned a pair of Adidas Gazelles? I quite like the look of them.
Best for me is the Nike Sweet Ace '83, comfiest casual sneaker I've ever bought

need to buy more pairs in various colours!
