I bought the Tony Little Exercise Sandals in the Summer in Zebra print. They have a 3 degree tilt, which makes the heel a little bit lower & it stretches out your calf, thigh & buttocks muscles. I had bilateral total knee replacements in Jul 09, so thought I needed to exercise my legs. I do deep knee bends, holding onto the kitchen counter & really feel the stretch. I'm looking online to see what I can get now in the way of a stationery exercise bike so I can row work my upper body. I had one about 25 yrs ago & I put my music off & pedal away. I have to work on my belly & arm fat. I've done a lot of walking & some running & still have shapely legs at 63. Got to get back my stamina so I can turn out my charity quilts that I'm behind on. I just changed Giraffe to Zebra above......sorry, got my animals mixed up.
