PLEASE HELP! WW1 or WW2 high knee leather boots?

[JBrunt]

Hello! I've come across these boots for sale for $25CAN. all I know about ww1 era boots is, They multiple layered leather soles, and sometimes have pull tabs with coloured stripes.

these boots appear to have multiple layered soles and striped pull tabs. they have high cut knees which I haven't seen before (maybe cavalry or some kind of mud boots?) and a heavy set of hobnails.

I would really like to buy these but I only collect ww1. Any help or info would be GREATLY APPRECIATED!!!
