i haven't seen the new ae dark brown shell. I hear they'll only make 50 pairs in dark brown.
They are crepe, worked great last winter on the snow and ice.
That Ravello shade is perfect!
I have a pair of suede LWB with double waterlock that I really like, but I usually prefer to have some extra cushion with the rubber sole for my flat feet.
If you decide to do it, you'd at least be able to show them off year round.
