In reply to thomascarr:
A lot of shoes sold as 'trail' are best on made trails and when it gets muddy, or you have a single-track/off-trail section the grip is lacking (and the uppers as well sometimes if you drag them through the crap.)
I've worn Akasha before, they were probably the comfiest shoes I've had. Did a lot of miles in them last winter (on the North Yorkshire Moors) but was slipping around a lot on footpaths. They were great on well-made tracks.
A lot of shoes marketed as trail have OK forward/backward grip, but the lateral grip is shocking when it gets wet or you're on a camber. I find this more true for continental models (La Sportiva, Salomon) than Northern European companies (Inov8, Walsh, VJ) - our trails are different!
I'd suggest going for something more responsive, with slightly bigger lugs that provide better lateral grip. Of course this can mean reduced underfoot protection and how you react to this depends how used you are to lower profile shoes and how soft the ground is (e.g. I live in knackered Xtalons and lower-profile shoes). Stuff like Inov8 Xtalon, VJ iRoc, Walsh PB, Icebug acceleratis are a bit more racey; Mudclaw if you're going proper rough-housing (though the uppers may not enjoy this too much); Inov8 Roclite, despite being marketed as a trail shoe, generally grip pretty well. I've not tried their new stud pattern, but their original model were some of the best and most versatile shoes I've ever had. The new Inov8 Terraultra may be worth a look as well if you can stomach the price.
