None of my local shops carry these shoes, and I was thinking about ordering a pair online. Does anyone know how they fit compared to Asics or Nike? I typically wear an 11.5 in Asics DS Trainers, Speedstars and Nike Air Zoom Elites. And a 12 in most New Balance. I’ve read online that some people recommend going up a half size in the Karhu, but some say they fit true to size. Anyone have any personal experience with them?
Not compared to those 2 brands, but I’ll give you a comparison to what I wear in case it helps:
About as narrow as pumas, more narrow than saucony, brooks, and adidas. I buy 10 in all those brands and have a pair of fast fulcrum rides in 10. I’d say they’re actually longer, but narrower. Kind of a weird fit.
Cool, thanks for that. I wear an 11.5-12 in regular Puma, and they fit well… just never run in them. I went ahead and ordered a pair of the Karhus, I’ll post how they fit in 3-5 business days 
Got my Fulcrum Fasts today (Forwards are still on the way). I normally wear an 11.5 in most Asics, Puma and Nike, and a 12 in New Balance. I got the Karhus in a 12, and they fit great. They’re just a little bigger than my Asics (which fit like a glove) but it’s OK. I think an 11.5 in the Karhus would have been be too small. They feel great, too, can’t wait to break them in.
