The Frye Men's Engineer Boot in Dark Brown is one of Frye's heritage motorcycle/engineer boot silhouettes — a tall pull-on boot with an adjustable buckled strap at the ankle, square-toe last, and Frye's classic Goodyear-welted leather sole. Hand-burnished dark-brown vintage leather upper that develops unique character with wear. Built on the same legacy construction Frye has used since 1863.Fit notes: Frye Engineer boots typically run true to size for most adults. The pull-on construction has no laces; the buckled strap at the ankle is decorative. Leather is stiff out of the box — expect 2–4 weeks of break-in. If you wear thick socks, order your usual size.Authentic Frye, shipped from Feet Heart — a family-run California shoe store since 2003. Free U.S. shipping, free returns, fit help at (310) 398-7497.
