Ok, have got up to 10 to 15 mins barefoot but thats it- I then have to stop because I get blisters on the bottom of most of my toes. I know it must be my technique but can't figure it out. I think I am curling my toes up slightly before landing and am trying not to push off of my toes but its still happening. Obviously between then treating said blisters and allowing them to heal my training is then very hit and miss. I intend to carry on with the barefoot, maybe get down the track and get myself videod and I may spot something but I am getting frustrated and having to stop my training in the meantime so am going to buy some barefoot footwear so I can continue to run. I am thinking of the Vivobarefoot Ultras - I got my daughter a pair and she loves them - likes running in just the sock too! Unfortunately there are no shops local that sell them so I would be ordering off internet - anything i should know about the sizing and what do you folks think of them?
