A Full, not half size small
At age 71, I don't think I'm still growing! My entire life I have worn a size 11 1/2. I am wearing as I sit here a size 12 black Merrell hiking shoe that is unbelievably comfortable (model no longer made). I wanted to add a brown shoe and selected the Moab Ventilator Hiking Shoe - Men's at a great price and appearance. I received them 4 days after they were ordered, fantastic. I tried them on and they looked great and fit well, EXCEPT my big toes were rubbing at the very front. In truth I needed a size 12 1/2, however they are not available in that size, so unfortunately I had to return them.
