If you follow the Grateful Dead’s Bob Weir on Instagram, you’re sure to see three things: set lists, live concert shots and workout videos. The legendary musician is actually quite the fitness buff, and, at 71 years old, he considers regular exercise one of his “Three Pillars of Happiness.” And if you look closely at the videos of Weir Instagram — on a rowing machine, with kettlebells, on an elliptical machine — you’ll almost certainly notice his distinct workout shoes.

In most of the short clips, Weir wears a pair of Vibram FiveFingers KMD Sport shoes. The unique toe-shoe style features a seamless 2mm footbed, a 4mm Vibram TC1 performance rubber outsole, a stretch nylon upper and hook-and-loop closures for the heel and instep. “They grip the floor well. And they pack real well,” Weir recently told GQ. “They pack flat, and they don’t take up any room because there’s no padding in them. You can’t beat that.”

Available in quarter sizes, these shoes include EVA arch construction for stability and they are machine washable. So if you’re looking for a responsive cross-training shoe that’s endorsed by a musical legend, pick up a pair of these for just $110.
