For spring, designers are ditching shoestrings in favor of sleeker men’s boot styles, making way for new shapes and leather treatments. Daniele Michetti’s supple boot remains rugged with a faded leather and wooden sole. Del Toro refreshes the style with a dyed suede and sneaker sole. Emporio Armani lengthens the upper in an unexpected woven leather. Sergio Rossi adds a formal touch with a brogue-style toe cap and double-buckle detail. While the lack of lacing streamlines the style, these subtle touches pull the aesthetic tight.
