I've been buying these running shoes for about 10 years now.  The last model I had was  version 10 because 11 didn't seem readily available in the US.  I wear a size 10 in street shoes but always need a larger size in these which is common with running shoes.  I have worn both a size 10.5 and 11 in the shoe so I ordered a 10.5 initially because my last model was a size 10.5.  Unfortunately, the 10.5 were too short on my toes.  My big toe was rubbing on the inside when I tried them.  I thus ordered the 11 which are just a bit loose but I can tighten the laces enough and they are OK.  The good news is that they were cheaper for some reason.  I was expecting more cushion with these new shoes and the toe box seemed tight but that could be because they are new.  I am a pronater and only run about 12-15 miles per week so these shoes help me and also help prevent the blisters that I get on my arches with other shoes.  I like the colors because they seem more current versus the older versions that contain mostly white.  So far, so good but I am not &#34;blown away&#34;.
