If you are looking at starting with minimalist type footwear I would suggest reading some of the helpful tips on sites like birthdayshoes.com and vibram5fingers.com
I played all of LL5 in a pair of Treksport VFFs after 5 months of MMA training and everyday walking/running in them. The only thing I had happen was a blister on the bottom of my right heel and a little muscle soreness.
Make sure to acclimate your body to wearing the minimalist boots properly and you will love them
