I feel with the Five Fingers Bikila running much more economical and the feeling to be able to feel the ground under his feet in all its nature, I do not want to miss. Especially on soft forest floor you fly only so then ... a dream! Top stones get a quick back to reality, but it can seriously injure one does not.
Even long distances over HM distance is not a problem. My Sunday route (22km) I walk now every week without subsequent soreness despite 1/3 cross country over hill and dale.
The longest distance was 32km far, so a marathon for a good preparation should also not be a problem.
In damp terrain the socks are wet immediately, one wrong step and the walk "floats" Amazingly, the socks but then after about 10 minutes again "run dry"
The disadvantages of shoes:
The quality of the sole:
After almost 250km the "glued" profiles are almost completely expired in the heel area. Especially in training sessions on tar, the profiles abrade in fast motion. Because each shoe 19 of Aldi is more robust. Since it must be done urgently something! I can not buy 5x in new shoes to me .... This criticism I have already read in other forums from runners. The simpler KSO will probably be much more robust, but do not have a profile.
?: With or without socks
I feel that running without socks as much more pleasant. Toesocks take a subjective 50% of the "barefoot feeling" and restrict blood flow. Unfortunately, one has moved inside the shoes in the area of forderen midfoot to which the skin is very thin and delicate, a seam ... because help on long trips just toe socks or short distances to 15km Vaseline ... also annoying!
After a kick in a dark puddle the shoes are hard to come by (even in the washing machine "clean.
Would not the indisputable quality of the glued profile and the seam in the area of forderen metatarsus which shoes could get full 5 stars from me
