So I know these are advertised to tone certain areas but when the 'senior citizen' friends of my Mom (in their 80's) started wearing them - I figured there must be a bit more to it.  Turns out these are WONDERFUL.  I spend a lot of time standing and walking.  My Tone Ups give me more hours of comfort that anything I've worn.  No foot, knee, back or hip pain.  As a bonus, I have been able to raise the thermostat 2 degrees since I'm not wearing socks and sneakers!
Mom and I are both prone to plantar fasciitis and I have chronic Achilles tendinitis.  We are both 110% satisfied!
You'd spend this much on sneakers wouldn't you?
