Today I rode out with the western Atlanta using the Barefoot Hip Saver.
It took a little while to get the fit tucked under the pommel and cantle. It does come in two sizes and as this is a size 2 saddle, the size 2 saver was perfect.
It does make a difference, giving you subtle support and the feel of a slight twist on the saddle.
I would recommend riders on a wide animal adds this underneath. It stops that sore stretched leg feeling, and enables you to ride in comfort.
It is also extra protection for the saddle having another layer between the seat and the base.
