If you are strictly using the boots for riding, I prefer a single welt leather soled boot. As mentioned before, a big, wide rubber sole will increase your chance of getting hung up if you fall.
I generally keep my ridding boots in the tack room of my trailer or he mud room of my house. I f I am not riding, I am not wearing them. I have muck boots for the mud, or Roper slipons for feeding/chores.
I never had much luck with Ariats, but I bought a pair for my husband years ago on Ebay
for $75 and he is still wearing them even though we have had them re-soled three times! I'm impressed.
I used to love Boulets but the quality has gone down. Last winter I bought some Anderson Beans and I was thrilled with them, but the leather is cracking already :(
I have an old pair of Paul Bonds but I hate wearing them because I don't want to ruin them....they are over 20 years old ...lol.
It just depends on the amount of money you want to spend. And I suggest if you find a good pair that you love, use them strictly for riding and find some cheap ones to do chores in.
