These size 13's fit somewhat large,  especially considering my last Portsmouth  [1's]  same size were tight.
I've had many many keens,  and they can be great shoes,sandals, hiking shoes,  but they definitely have a size quality control,  a size 13 can be too large on one 'model'  and too tight on another.

these are comfortable with somewhat extra cushioned socks,  and they look good
