It does indeed.
I've tried many searches on the words "canvas ankle boots" looking for what the original boot might have been. The searches led mostly to boots used for boating and hiking.
Turns out the ones pictures above are described as "dinghy boots".
If they have a square-ish toe it's looks like it might be a suitable boot with a little modifying. They're not canvas. But since MC boots don't seem to grow on trees, the rest of us have to find something to wear.
Keep us posted Neil! 
Cheers!
