If available where you live, check out the Keen brand of hiking boots. Typically, they have very roomy toe boxes. I am on my second pair of Keen Targhee II boots, after five Caminos. I got four Caminos on the first pair, albeit with two resoling services folded in after the first and second full
Camino Frances.
I found that the soles are only good for about 1,000 Km before the tread wears down. But, that could be marked up to my feet and walking style. Your experience may vary.
But, caveat emptor, regardless of which brand and style you choose, always check with the manufacturer concerning whether the particular style runs small or large, versus the quoted size. For example, Keen states (or stated) that their Targhee II boot runs 1/2 size SMALLER than marked. Hence, if you needed a US size 11.5 boot, you must size up to a size 12 to get the true fit.
Also, and as discussed elsewhere on the forum, you should buy your boots a minimum of one full size larger than your street shoe size. This allows for daily foot swelling from heat and moisture, and another one half-size for the second pair of socks one ought to be wearing to reduce friction and increase cushioning.
Personally, I have long advocated that 1 and 1/2 sizes extra are best. That allows 1/2 size for swelling, 1/2 size for the socks, and 1/2 size for the splaying or spreading of the foot that occurs after you have walked several weeks with a load on your back. In my original experience, my street shoe size US 11 feet required a size 12.5 boot. But, as discussed regarding Keen sizing, my Targhee II boots are marked as a US size 13 (EU 47).
I hope this helps.
