Don't you just love practicality? Amy chooses to dress location appropriate in The Impossible Astronaut and at the beginning of The Day of the Moon with a pair of hiking shoes from The North Face. I don't think this particular colour combination is still available, though these shoes turn up often enough on resale sites for them to be found eventually, and I don't think there would be a lot of competition for them nowadays when they do. However, The North Face is a very trendy outdoor gear brand, so there would likely be competition from non-cosplayers for them.
The product name is quite a mouthful, and I've seen them described in a myriad of colours including 'shroom' which I quite like, but fossil/ivory seems to be the correct title.
Here's North Face's sale specs if you're down with hiking shoe hype:
"These lightweight, low-cut boots from The North Face are both waterproof and breathable thanks to a Gore-Tex® Extended Comfort Range membrane on the nubuck and suede leather uppers, and also feature abrasion-resistant mesh, protective toe and heel caps and gusseted tongues to stop debris creeping in. Cushioning and support is provided by ergonomically designed Northotic® footbeds, while Heal Cradle™ and Snake Plate™ technology contribute stability by keeping heels and forefeet where they should be. Vibram® rubber outsoles on The North Face Women's Sable GTX XCR hiking shoes add sticky traction over varied terrain, keeping you sure-footed and equipped for the challenges ahead."I do love me some sticky traction™. If I were The North Face I would be trademarking sticky traction. Maybe Sexyland beat them to it, I don't know.
Anyway, I don't own these because they're not really my style and I basically go outdoors only to go back indoors. I do have a pair of Merrils which I got when I was backpacking, and they're similar enough to be pretty darn good alts.
