Reef Fanning X Mlb Men's Sandals. It was one of those "duh" moments, when we brought them together: our #1, iconic Fanning sandal and your love of MLB. The result? A water-friendly, stadium-ready, tailgate-happy sandal. Compression-molded, high-rebound EVA sole with a built-in airbag, plus a soft strap lining keeps you comfortable, and yes, our famous Fanning includes a built-in bottle opener, to see you through all those grand slams.. . . .
