SEOUL VEGAN THONG 051225INTENTIONALLY BLANK SEOUL VEGAN NEOPRENE THONG SANDAL The SEOUL summer flip flop is not a regular flip flop, she's a fun flip flop. The padded and puffy scuba upper, pads and holds the foot on our oversized, squared off sandal footbed. This style is so fun and eye catching, but the subdued colors keep it very elevated and fun just like the city we named it after.
