I wear a size 11M in US size and have worn Saucony Omni's for the past several years.  I ordered these because of the reviews of great fit and stability, they were just OK on the stability side; however the 11M US was extremely tight and my toe came to the very end of the shoe.

I returned them, of course great customer service from the supplier and Amazon, and ordered a pair of Saucony  Guide 3, i couldn't find any Omni's in my size, and experienced the same high quality stability i have had with my last 3 pairs of Saucony's Omni's, and they even seem a bit lighter than the Omni 9, my last shoe.
