Rare is the winter boot that's both warm and easy to pack, but Teva managed this combination with its Jordanelle (women’s) and Chair 5 (men’s) boots. The lightweight winter walkers fold down to the size of normal shoes while touting the benefits—rubber soles, waterproof uppers and sealed seams—of bulkier boots. Bonus: The removable boot liner makes a comfy slipper for fireside lounging.
