Ankle shoes with toggle fastening apparently were in use for about 200 years, from around 850 to 1050 AD. The shoe reconstructed here fastens with a single flap and toggle. The majority of the finds of this type from York are dated to ca. 930 - 975 AD.
This turnshoe is made of a one piece upper, stitched to a sole with a triangular heel extension that is typical for this type. The upper is calf, the sole cow leather. It employs a tunnel stitch construction except for the area of the v-shaped heel extension of the sole, which is done with a flesh/edge stitch.
As the two holes at the seat and the tread of the original sole shows the shoe was made on a last.
The upper edge of the shoe shows traces of stitching but no indication of a top band remains, which is why I decided to go for a simple whip stitch decoration.
And here comes the big blooper: I didn't read the description carefully enough before starting and assumed that the closing flap and toogle would be on the lateral or outer side of the shoe. Which it isn't! This type of shoe actually was closed on the inside and seeing how low and far back the toggle comes to sit, I think it is well enough out of the way. Well, I guess I'll have to make two more shoes to have a pair ...
