When my podiatrist suggested surgery for my inward-tending pinkie toes, I went immediately to minimalist shoes for everything - walking, hiking, running - and barefoot whenever possible. My sidis are an exception, but they are all leather so they "give" somewhat at the toes. When I got rid of all of my synthetic narrow toe box shoes, my toes magically started feeling better and even straightening out some. When you walk barefoot, you strengthen everything in the foot, helping you to spread out those toes and walk more efficiently. Try it!
