I have seen a set of plans for a work boot. They were for a pair of boots made from leather and wood. If you want to make a pair of boots like the ones in the picture, the first thing you need to do is find someone who works at a shoe or boot shop and has access to a large variety of tools. Anyway, I think it's best to order a good pair of boots from https://rockroosterfootwear.com/collections/ak-australian-collection. I ordered it last year, and I think it's the best one nowadays on the market.
