There are various spur designs and various rowel (the round part of a western spur) designs.
Barrel spurs clip onto the heel and have soft "bumps" on the inside. That is probably the softest spur you can find.
Moving up from that, there are "english" spurs. Instead of a rowel, they usually have a small round ball at the end.
Up from that is a western spur, which has a rowel that turns.
From what you describe, the previous owner most likely used a western spur. If you are going that route, you might try looking for a "cloverleaf" type of rowel. That has no spikes or sharp edges.
For a good picture, see: Rowels - Smith Brothers
From the pictures, you can see how something like the twelve point is less soft.
