Saucony Grid Tangent: My road running shoes, great for longer distance runs on the tarmac. So, basically my mileage shoe. They have a nice but of support, sufficient for what I need anyway. They are also very lightweight and so ideal as a racer or for faster paced training runs.
Inov8 F-Lite 230: My favourite shoes by a mile! A real luxury to have and a real bargain at 35 quid off Ebay. These are basically really lightweight (230g) trail shoes, ideal for road, canal towpaths, forest tracks and anything similar. I use them for very fast paced training sessions such as Tempo runs and Fartlek. Many people would say it is a waste of money to have a shoe like this, but they feel so good and I just love light shoes (who doesn't?!) , particularly when they are as responsive and asthetically pleasing as this. And nope, they aren't flimsy like you might expect.

More Mile Compression Socks: The running world has gone mad these things! They promise to improve circulation and reduce lactic acid build up. I was a little sceptical about them to start with, but considering so many people had started wearing them, I decided to try them myself. I don't regret it one bit so far. They really make your calves feel good, and I certainly noticed the difference in recovery after sessions. Top stuff - I might just buy another pair I think!
