Again, try them on, fit is so important.
My old ones are Meindl full leather. I bought them for my gold DofE about 18 years ago and only this year has the rand started to crack. Leather boots are tough but heavy and a bit hot in summer/warm climates.
My other boots have been Berghaus fabric goretex things. Basically outdoor trainers with ankle support. Much lighter, good for hot countries and travelling but I get 2 years out of them at most (where the two years included a couple of walking holidays -Iceland and Ethiopia as well as local stuff on the moors).
I guess proper leather will be out of your price range?
Other kit I have from Decathlon is good so they may be worth a go if there is one near you. Go-outdoors may also be worth it.
