I haven't hit the $75 mark yet. Three years ago I worked a show for 5 - 10 hours days on my feet with no break and bought a pair of Nunn Bush gels at Sears for about $60. Still wearing them for high usage shows. Walking 4-6 hours a week I cycle through NB or Nikes at $50 a pair until I'm putting duct tape in the heels. I guess I don't have fussy feet.
I've also been known to walk 3.4 miles wearing flip flops in Key West after a night of discovery.
Took SS at 62 and hope I live long enough to regret the decision.
