ALLBIRDS TREE RUNNERS

When this San Francisco-based shoe company took flight in 2016 with an environmentally friendly merino-wool runner, techies in Silicon Valley and millennials everywhere went berserk. This year, Allbirds launched a new textile that’s engineered from eucalyptustree pulp and knit into a mesh fabric for a soft, four-way stretch. The Tree shoes are lightweight, machine washable and a magnet for compliments – little wonder eco-warrior Leonardo DiCaprio is now an investor.
