What really won me over was when we were having a heatwave and I was recovering from my wisdom tooth extraction. I was going out for long early morning walks and in place of my running sneakers, I wore my Allbird Loungers. Since the merino wool is lightweight and breathable, the shoes kept my feet cool in the heat. I walked over 10 miles before my feet got tired. I’m looking forward to these also keeping my feet warm as the temperature cools down. Unlike many of my sandals and ballerina flats, the Allbirds are really flexible so I can jump, squat and have a good time without worry about them hurting my feet.
