Jack Rogers Patriotic Sandals

Jack Rogers Embroidered Patriotic Star Sandals, Women's Size 6. Originally purchased for a reception shoe, however, after 2 wears, the heel pad on the left shoe just fell off. The brand was unable to replace this piece, and I'm unsure how to do so myself. I believe the shoe could be repaired by someone who knows what they are doing. Sandals have only been worn twice and are like new besides the heel pad missing.
