Not Barefoot!

I have these shoes about a year now.
After I have mostly worn barefoot, I had to increasingly determine the run of the year, that they began to smell.
I do not have sweaty feet and a lot of sports, but I could get on their feet ever problems.
However, I wear the shoes then sometimes even 5 hours.

Anyway, they now smell so unpleasant that I, despite the already since longer socks to wear, and the smell no longer get out.
Even a washing machine gear has it can not change anything.
So important tip, not barefoot and certainly not too intense wear.
Otherwise, the shoes are excellent in pass and comfort during sporting loads.
