I am not impressed by the tanning process.  I bought these boots from a local shop and a few months later got diesel and grease on them while working our yard.
Got home and used saddle soap on them, now the boots are 2 different shades.  When I apply some polish, one will shine and the other remains dull.
The boots themselves work as intended, the fit of the boots are bad though.  They way Ariat cuts the top of the boots made me go UP a size from my normal size.
I will not be buying another pair of Ariats, their tanner does not his job very well.
