We've had a bout of bad weather here the last week or so (see pic) and I've once again seen the wisdom of buying a decent set of ice walkers.
Around this time last year, Mrs Doombreed and I invested in a set of Yak Trax each, and they're about the best purchase we've ever made.
What's astounding is that they were significantly cheaper than most others available, and yet they're amazing. They simply stretch over the sole of your shoe and provide excellent traction over the smoothest sheet of ice.
Don't go sprinting in them, of course, but normal walking speed is easily possible.
Credit where it's due, Yak Trax are outstanding.
