Excuse the face in the picture, Im not very good at pull ups hahahaha! I live in Michigan and have only worn these boots outside, socially, for a couple hours at a time in 20-30°F weather and my feet were frozen, but not numb (as they would be if I wore tennis shoes)Im convinced that there are boots out there that will keep my feet warm in frigid weather, while supporting my high arches. With some work it could be a good product, but for any airpods user I CANT RECOMMEND this at all. Edit to add: I just realized these are not returnable! The quality of Sennheiser earbuds has definitely gone downhill over the years. Für 3-4 Personen ist es ein gutes Konferenzsystem. Very easy to install - just two screws in the central ladder and the rest hooks on. Overall, a good deal I finally decided to invest in some quality headphones. Fits perfect for a 2018 Ford Explorer
