For me, the most comfortable are my (soft sole-their specific feature on some of their shoes) Birkenstocks. I like the open toed sandal style and although I look like a total nerd, I do wear socks with my sandals when my feet become icy. The shoes aren't cheap 125+ but totally worth it for their comfort. I find that I do not need to wear my orthotic with these shoes. They provide great arch support. min
