I have been running competitively since 2012. Initially I was getting injured a lot, so in 2014 I started to work on learning proper running technique and switched to Vibram FiveFingers. Since then my injury rate has sharply decreased (I have been injury free for over an year now) and my performance has improved greatly (placed 1st Masters in the 2 marathons, and 1st Overall in the one ultra marathon I have completed recently). As an added benefit from wearing Vibram FiveFingers my posture has also improved and my legs get less sore/recover quicker.
My favorite training shoes are the Spyridon. They are very durable, yet light and responsive, which makes them well-suited for both road and trail running. For road racing and especially for marathons I prefer the V-Run as they are very light, yet with just the right mix of ground feel and cushioning.
