Looking for a first pair

Hello, I'd like to by my first pair of boots but i don't really know what im looking for, right now I am using what I can get my hands on, one old pair bullterier about 2 sizes too big, and before that I had old running shoes( not recomended, ik). I know that boots ain't cheap, however I dont have high budget. Any advice you can give?

Now here is the important stuff, not in america, so stuff is around 5 times more expensive. I can use amazon, ebay and most other online stores tho
