I can't get my wide feet into 333s, while the 272s fit me pretty well and I am disappointed that Inov8 have discontinued them .... as Hank says, they're getting harder to source - I know this, I ordered a pair from PBs yesterday (my 4th pair), there aren't many other retailers who have a full range of sizes. Get 'em while you can.

I pray that Inov8 have done their market research and that the 300 is accessible to us fat-footed types .....
