Giesswein Merino Wool Runners,US 8 EU 39

Worn once. Great condition tennis shoes made of Merino Wool. Very lightweight. Flexible sole. From manufacturer: "Naturally odor resistant, you can run all day and not worry about a smell, even when you aren’t wearing socks!" Color: sandmele (light brown). Size: US 8, EU 39. I wore these shoes once for about one hour. Unfortunately, I stepped in something (grease??) that left a quarter-size stain on the bottom of the sole (see photos). Shoes come in original box with second pair of black laces.
