Got 11.5 4e and they are amazing. Very roomy so I put an extra liner inside (excellent ones from ILoveSia). I have an oddly shaped foot compared to most - the outer wide bone sticks out to a point compared to most thin and rounded. Thus, ordinary shoes or even ordinary wide shoes can cause severe pain where they cannot be worn. These shoes overcome that by being comfortable, almost like dress shoes, which is a must for my job, and they don't slip, which is great too. I will for sure buy again.
