Thanks for adding your review to the thread stumpy!
So i got the 12 and 11 wide today, and here is the deal.
The 11 wide alleviated the crammed foot issue, but there were some odd issues with it that made me end up choosing the 12's.
For some reason my heel sat much higher in the wide shoe, it was not sitting where all my other shoes do and provided poor grasp around the back of my foot which would lead to blisters since my heel kept popping out ever so slightly when i walked. Also, the in-sole tended to slide around a little if i planted my feet with a wide stance and shifted around like i was moving something heavy, even though i had them laced up snug and they did not feel loose at all. This tells me they are designed to be a tight/snug fitting shoe.
The 12's are a good fit, and i have about a thumbs width from my big toe to the front of the shoe. More slop then i have on my normal pairs of shoes, but not enough to make them uncomfortable or a bad fit, just something i noticed. (this may be personal preference to a degree, all my shoes i like a snug form fitting size, boots i leave a little play in the front to account for larger socks).
So if you are going to get some Altama's go up a size for sure or i can pretty much guarantee you will have width issues on the front half of the foot unless you have a really narrow foot.
Additional review to follow once i get these in the water today!
