Carefree and comfy, the ACG Moc returns to its roots: ultralight, perfectly shapeless and brilliantly versatile. Originally named the "Air Ida" (for its striking resemblance to an Idaho spud), this surprisingly sleek potato-sack-of-a-shoe might just be the savior of civilization, er comfort. The breezy linen upper delivers summertime style, perfect for basking in birdsong and wild vistas. And when the temps drop, insulated materials will help keep you cozy around the fire. Open the hood and check out what's new: A drop-in midsole takes you to cloud nine, while the updated lacing system locks in your fit. Slip 'em on and take that sunset jaunt—just be back in time for s'mores.
