For comparison, a 100# woman in high heels applies about 1500 psi!
Is that when she rocks back on only one heel, or both? What about when she stands flat footed? C'mon man, this is PondBoss after all, we obsess over the details!!
Example: 125 pound person wearing 1/4 inch square spike heels. Rocking back on both heels = 1,000 PSI per heel. Standing on one heel = 2,000 PSI. Hundreds of people walking back and forth in spike heels = one sheepsfoot roller. LOL
