The brand Allbirds may be relatively small in China, but it is very popular abroad. It is a San Francisco brand invested by Leonardo, focusing on comfort and environmental protection. His wool shoes are known as the most comfortable shoes that can be worn barefoot. Eucalyptus series sports shoes are not only comfortable to wear, but also the whole pair of shoes are made of environmentally friendly materials. Are they particularly outstanding? I'm a fan of Allbirds myself. I can put everything in the shoe cupboard, but I always have two pairs of his shoes.
