“I bought the Uppsala Sherling boots because I have Plantar Fasciitis which the boots have helped tremendously. I prefer Ugg boots, I like the way they look and are so so warm, however they aggravate my already aggravated Plantar Faciitis. If you have foot pain, Birkenstock’s are the way to go. I wish they were warm like my Ugg boots, but sadly they are not. I have had to trade warmth for controlled foot pain.”
