So these started life as a pair of hand-made, custom moccasins I purchased in the little town of San Pedro, on Lago de Atitlan last year in Guatemala. They were handmade by an awesomely skilled Mayan lady, and I've worn them in all seasons since then. (Add some breadbags and wool socks, and they're fine, even in a Maritime winter)
However, they were kept on by two very long leather thongs that have to be wrapped around the ankles. This is fine most of the time, but at places where you take your shoes off inside, it becomes bothersome. Also, I wanted something period in the way of viking footwear. The general construction is very similar to 10th century footwear finds from the Viking age, so, I set to it.
I cut and trimmed one flap into toggle, then unable to acquire wooden toggles, I made my own using old paintbrush handles, a file, and a blowtorch.
Some correct lacing, and bam! Jorvik Boots.
Still retain the spirit of the originals, but with a Norse flavor.
