filli fabbri, tucci, parlanti miami ESSENTIALS (the cheaper parlantis last longer), tredstep medicis or tredstep donatello II, i'd avoid the cheapest model of ariats (the heritage contour i think?) for me, they only lasted a year (i rode six times a week in them and worked at the barn in them so depends on how much youre wearing them)
sergio grasso! they are almost like customs! they do stretch a tiny bit though
I really like my Ego 7's. They're inexpensive too.
I agree with Chloe Gordon
Ariat Heritage Contour Zip Field Boot
Brogini not to expensive but last a long time mine were £110
Ariat contours are what I have and they are so comfy once they're broken in!
