Just received them today.  Much sturdier than expected.  I followed the suggestion and since I usually sear a 9.5, I ordered 10.5.  I think I could have gotten away with a 10.  At least with the extra space I can squeeze in sox when it gets cooler.  The next pair will be 10's, tho.  Due to back problems, I won't be running in them, but I prefer the zero drop sole.  Strangely easy on my knees.  That sole is thin, but stiff so the occasionally rock won't kill you.  After a little wear, I'll come back and check on that 5th star. Finally realized that my eyes aren't playing tricks on me.  My black shoes are actually dark navy about the color of the tongue and laces in the pictures.  Not bad, just not what I'd ordered.  Love the shoes, tho.  I may try to get the black again sometime, but will go for the orange 10&#34;s first.  Down a half size.  If they can get this right they may get that 5th star. Just got the second pair today.  Sized down to 10's, so half size up is the way to go.  If you're expecting a really crisp black, you's be disappointed.  They are still a dark navy blue, but are also still about the best deal to be found.
