Try any of the new “toning shoes”, they really don’t “tone” your legs as advertized, (well, they must a little, because you use slightly different leg and calf muscles, but I haven’t noticed any visible diff.), But what they do, do, is instantly give you “perfect” posture, and take all the stress off your toes and heels. (The “posture” part is enormously helpful for back pain, etc.) After 14 hours on my feet, I still feel like I’m floating on air!! (I’m 6 foot tall 250lbs, 57 years old, and male)
