Mine are "5 Fit", which means they're full of marketing bollix. I have pretty wide feet.
Tbh, I bought them not for fit or function but because my first Dominators lasted over 15 years and I only retired them because the soles had worn so the cleats were wearing on the ground (granite setts around the office). For cycling, they were still fine, but two pairs of cleats a year aren't cheap. The new ones have already needed a replacement buckle - a potentially ride-ending fault - so these will probably not do 15 years.
