Shoe:
It is very light and wears the same way. I personal think the non-removable "insole" pleasant.
In the heel area he gives good grip and is so well padded that you can slip in fast times but without him and tie.
Steaming does the Flex sole very good.
Processing and optics:
The Flex sole is made of a soft foam billigwirkendem what triggered skepticism but it is so convenient that I ignore that. In addition to a shoe of the foam is squashed and looks a bit unsightly (for the point deduction)
The laces are flat - I may prefer round but maybe.
The shoe is pleasantly air-permeable but not nearly as I except it, there he is indeed almost entirely of mesh fabric - it is not so in milder temperatures too cold at the bottom.
And yes you sweat in the shoes, but in which normal shoes when I / rumrenne to work 12 hours straight in the area does not sweat the feet ???
Seams make a very good impression, the bond looks clean.
Conclusion: I'm wearing it now two weeks every day and regret not buying (have 26 paid at full price, the shoe would be on account of the ugliness foaming declined) and carry him very much, just have to find the my other shoes now feel heavy and uncomfortable like in old times
