Just window shopping but ... as someone who always keeps one eye out for a better way I enjoyed the "Sims" (larger image>waterflow) as it seems a step forward but still think that for portaging purposes honest to god drain holes that kept out sand if not mud would be nice.

I really hate Flash but the SAR type had laces that made sense plus looked liked like they'd fit best under a seat. The common footbed "sim" was interesting as well. Personally I like to get a feel for what I'm stepping on so I take the one from the different brand of boot I own out plus it fits better when wearing GT socks. They are useful though as that's what lets the water drain out as designed.

And FWIW - I'd expect the fit to be intended towards the tight side. I sometimes have to remind myself to lace mine up (different brand remember) for the more interesting portages.
