As for the Amok sizing:
9D in 5 last fits bigger than 9D in the Amok (I forget the last).
The amok's last is more narrow than the 5 last.
As for the the quality:
For the most part, AE makes fantastic shoes, but the Amok is not one of them. I purchased first quality Amoks for $100 six months ago, but had to ultimately return them due to quaity issues. I guess for $69, there's not much to lose, but I wouldn't expect from a quality perspective.
