I recently discovered GoLite's line of shoes, which are made by Timberland. They are not cheap, but I just snagged a couple of last season's Sun Dragon design for about USD$50 a pair.
I like these shoes because:
1) they are made for trail running so they have great stability;
2) they are super breathable (and my feet need that!);
3) they are really lightweight, and since I wear an 11 my sneakers are the heaviest thing in my bag.
My email inquiry to GoLite's customer support assured me that all of their products are made with synthetics and no animal products. In the US you can find the shoes at REI, EMS, and other outdoor sports shops.
