This is my 2nd pair of fit flops as I wore the other ones out after having them for over 3 years.
I live in a hot climate and walking the dog twice a day for 30 minutes each time I need comfort and support.
I have not really noticed more fitness because of them as I am pretty active anyway......well OK my legs do seem to look more toned but that maybe is recent beach walks or bike riding. Not sure. But I love these shoes as regular sandals or flip flops make my feet hurt when I walk in them any long distance. Buying them on Amazon seems like the Best price.
