"We call it a Flatbottom. Some call it a Bell. No matter. This all-around stirrup is built slightly wider across its base so your boot sits comfortably on the tread, unhindered by the stirrup sides. A slight rise, like an arch in a shoe helps set your foot for a good ride.
 
“The Leveler”, available only as an addition to Nettles Stirrups. An unleveled stirrup causes a foot to tilt, stressing the ankle. Like sand in your shoe, even the smallest tilt can cause discomfort. “The Leveler” may be added to any new pair ordered or you may ship your stirrups to our facility to have “The Leveler” added to your favorite pair of Nettles Stirrups. Price per pair.
