Big fat slow centre half with wide size 11 feet? Are you sure you’re not me?
If you can find them Umbro Speciali are wide and fit me well, Sports Direct have them occasionally. More readily available are Adidas Questra, I had to go up to a 12 (Sports Direct have them) but they’re fine as well. Not sure they do astro’s but if you can find them, the UnderArmour boots are wide too, almost too wide for me which is very rare.
Hope that helps!
Edit, looking on the Sports Direct website they have Speciali’s but not the right ones, you need the proper ones that retailed at £70 ish (but never sold for more than 50% of that) not the crap plastic ones they now have.
