This is a really nice wool shoe! I really love this negative heel technology and have worn the earth Kalso shoes for years. I’m sad that they seem to be phasing it out. I was afraid this style would have a dowdy look but they look very sharp on…only thing is they seem to run a little small especially if you have a wider foot. I wore them for one day. They might be perfect for a narrow 39 otherwise I’d recommend them to someone who wears a 8 or 38 in Earth or Dansko shoes.
