But here are my boots
http://www.tackroominc.com/images/AriatGlacierChocZip.jpgI spend a lot of time in these boots and I love them, not a traditional type 'english' boot as they have fairly thick soles.
I will have a look into the ariat ropers, but still not sure if I could do the required running in them, boots are really hard as you don't get to try on a lot of the western type boots over here.
