5 star rating for literally the best shoe ever. I wore these almost everyday this summer. They are so incredibly comfortable. Cushion and padding is wonderful makes walking and wearing them very easy. They are not to platform at all and they don't have a separate heel height from the rest of the shoe so you're on a even walking ground. Size is perfect I stayed true to size and ordered my original sizing in Ugg which is perfect. The style os so trendy and literally goes with everything. I highly suggest them. I have back problems/ back surgery and these made my life so much easier. Comfortable and great support.
