Not sure where to post it; it looks like it's a good olace

What you have there appears to be the archetypal "oubliette d'épinard" (pikeman's camp-sandal), the design is of Gallo-Roman origin and would allow footsoldiers to warm their feet around a fire while also roasting meats and vegetables.

I'm pretty sure it's for climbing trees.

Typically there would be a rope that is held around the tree trunk and gets shimmed up the tree.

Op here, according to my grand father the sandal shows marks of arc welding, so it can't be really old.
Moreover, boots used for pole climbing are like pic related
Any other ideas ?

That's a batonning shoe. You couldn't tell what it is because it's missing a few pieces. This is what the complete one looks like

This is for climbing poles, like, telegraph/telephone poles etc.
Poles had holes, you put those on your shoes, put a special belt, d you climb up to fix the telegraph, so that ount Stephanny can send five dollars to her nephew in Tsar Russia, for which he will buy ship ticket to America.
