Sole of the Putter

It is good to have a radius on the sole of the putter (when viewed from the front) to accommodate slight differences in body posture or certain ball position preferences. The radius will also prevent the toe or heel of the putter from snagging when there are severe undulations and uneven lies on the green.

The Frankly Frog has a radius sole designed specifically for these reasons. Build your own by clicking here.
