I have been wearing nothing but Orthaheel flip flops and sandals for a couple years now, because of some tendon and heel soreness. Orthaheel shoes fixed my foot and heel problems and now I was just looking for other brands/styles that I could wear to get away from the same look and feel. When I first put my foot into these, the feel of the shoe was really nice. I love the curves of the foot bed and it had a soft feel. The first couple steps were a bit stiff feeling but pleasant. Wore them the next day and they felt a bit hard on the foot. You need to keep the buckle strap somewhat tight or your foots sets down on the shoe wrong when you walk. To me, standing still feels way better than walking in these. Very comfortable to stand in, but walking, although it feels like proper alignment when stepping, just doesn't feel as good as a softer sole flip flop. I believe orthotic flip flops allow the tendon on the bottom of your foot to stretch more when walking, since only the top ball of your foot is secured in the shoe, allowing your entire foot to stretch. It seems when you have the back end of your foot strapped down to a harder, less flexible sole that doesn't bend, you are losing some of the natural stretching your foot makes when you walk and you make smaller strides because of this. I do like the shoes, just think wearing this style long term may limit flexibility.
