I have been a fan of vibram five fingers for a long time but I've never ran in them and after running for so long with a traditional running shoe and always having aches and pains I think it's time I looked into learning. I bought a pair of brooks purconnect running shoes to make the transition in and have done two mile jogs with a mid foot strike and my arches are sore. Is this normal? How many miles should I initially be starting out with? Seem like there's a lot of conflicting information on the world wide web so real world advice would be awesome! Thanks.
