Crepe soles seem to agree with Frye standards of production, as this is my third pair so-soled, and all three of them seem to be holding up well.

This black wing-tip is no-fuss.  I would not wear it to be married in.  The crepe soles just a trifle casual.  Would not wear it to a funeral, for the same reasons.

But for "casual Friday" and semi-dress, a black wing-tip that straddles the line between between "formal" and "casual" has a great many uses.

Frye is well regarded for quality and durability, although  some buyers of Frye shoes and boots have been disappointed with such issues as sole separating from the shoe, among others.

Thankfully, no such issues with this wearer of this venerable brand.
