These fit bigger than other sneakers so I had to size down. GS said they are B Grade, but I have not found a single flaw. I shared pictures with @aerosurferlv (Dale) and he couldn’t find a flaw either. If you are a 13 in a margom-soled these 12’s will fit you great. This leather is veg-tanned natural minerva from the Italian tannery Badalassi. Will patina and SLIGHTLY darken. I’ve been wearing mine for about six months and they are the best sneaker in my closet. TONS of compliments. Description The Coast embodies a dress sneaker silhouette while using our favorite vegetable-tanned leathers. The thicker upper leather handles everyday abuse without concern and will age similarly to your favorite Goodyear-welt boot. This article is made in one of Italy's boutique tanneries which specializes in vegetable tanning. The leather is placed in a 'Bottali' which is a large barrel that rotates allowing the organic tanning substances to stay in contact with the article. A complete cycle may take 30 - 35 days. This leather is durable, has the scent of a saddle room, and ages beautifully. Prominent vamp breaks and a variation in color should be expected with this type of bovine leather.
