The tongue is far too short on these shoes and the soles are made of soft material I'm a western man who weight is 102KGs so the soles need to be made of a more thicker material the size 50 and the length are perfect for westerners The last 3 pairs of your shoes you added extra insoles this time none were added. You need to make other designs of your foot range in the larger size as in 48/50 as western men who all have large size feet are searching online for extra large shoes, sports shoes, runners, and work boots, none are available,
Very good quality and it is what it looks online
