@ granto:
I wear 9-9.5 regular width shoes, and I could feel the outer edges of the pedal dig into my feet, and also rolled off the sides when pedalling. It got annoying and my feet were not supported enough.
I don't know how they will work on your size 11 shoes unless you have really hard soles. But I hope it works for you.
I sold mine on Clist and broke out the old MKS Touring pedals and they have been great.
No tab needed to spin them on. You could always put an MKS tab into the Tourings if you really want them. They have them that bolt onto the back of the pedal.

Touring pedals have been fine while wet with their ferocious teeth.
