This Yves Saint Laurent T-strap sandal ($995 at Yves Saint Laurent, 3 E. 57th St., nr. Fifth Ave.; 212-980-2970) stars the designer’s latest heel, a shape that’s gaining on the ever-popular Tribute sandal’s narrow little spike. The Robyn, as this model’s called, is a futuristic stack of silver swoops that elevates but offers a bit of balance, too. YSL’s runway was full of tweedy suiting and polished French-lady coats, but this shoe would look just as good with the season’s wild fur or utilitarian parkas, or peeking out from beneath a pair of very slouchy pants.
