First impression after about 15 km: The shoes are well made and see quality from. The sole is very suitable just for gravel roads, a good compromise between stability and flexibility. Good grip due to the profile. If you use sports and trekking socks should be chosen one size larger. Could the shoes very high heat conditions not test, to 23 degrees, there is no smoldering socks. More information to follow - until now - buy recommendation on my part.
