I usually wear a 9.5 SS in Munro. In sandals sometimes I wear a 9N. I ordered these from Nordstrom in 9N first, since Munro did not carry these in SS. They were too loose all around. I then ordered these from Munro directly in 9SS, but the strap near my toes was too tight. So I will need to order these in 9.5 SS - they are definitely running true to size. They have a harder sole than my other Munro sandals - beter as a dressier sandal - which is how I intended them. Very stylish.
