Allbirds is doing Cyber Monday 2020 differently. Instead of offering markdowns, the eco-conscious fashion brand, known for its comfortable, minimalist sneakers made from natural and sustainable materials, has released limited-edition styles of the Tree Dashers — performance shoes that display their carbon footprint number of 9.0 kg CO2e on the outer sole. The company has redefined holiday shopping season with their unique Black Friday and Cyber Monday events.
