Sierra Trading Post recently received a shipment of Merrell Trail Glove shoes, and pretty much all men's sizes are currently available (sizes 7-15). The price starts at $82.50 (plus shipping), but if you subscribe to STP's dealflyer emails and have a extra 35% off coupon laying around, then they are $53.62. And if you have a STP credit card, UPS Ground shipping for most items is flat-rate at $2.95 per order.
Trail Gloves have been my primary running and around town shoes for the past 8-9 months and I'm just about ready for a new pair. I'm not sure I would recommend them for backpacking – maybe, depending on how much you've trained up your feet to the barefoot style – but they are awesome minimalist running shoes.
As a bonus, I have a coupon code for an extra 25%-35% off, good for two more orders (actual discount is dependent on undiscounted order total – extra 25% off for orders of $75-100, 30% off for $100-125, and 35% off $125+): TPX0855X
Edit: My attempts to post an html link to sierra trading post has been a huge fail… can't seem to get it to working for me.
