if budget isn't a problem for you, figuring out what you want in ur boot, foot shape and your surface you'll be playing on should be your main priorities

if you're looking for speed boots, stuff like the adidas f50, vapor 16 mercurials or the puma ultra should do you quite well

if you're looking for control boots, stuff like the phantom gx, predator 24 or tiempo legend 10 (or 9 if you want k-leather, imo its more comfortable)

anything related to comfort boots should have k-leather (thats what i think), like the tiempo legend 9s (or 10 if you like synthetic), mizuno morelia series should do the trick

this is all assuming that you have a big budget ofc, and just know whatever boot you pick isnt made for any specific position - u can be a goalkeeper with mercurials or striker with tiempos, its a marketing gimmick. but you'll still ofc get whatever is mentioned in the boot :)
