Sperry Top-Sider Crest Vibe Linen Oat boat sneakers size 11

Sperry Top-Sider Crest Vibe Linen Oat sneakers in EUC ( worn only once to the beach). Women's size 11. Fits true to size ( I'm 10 1/2, so is a bit too big. I've tried adding stick on pads , but my foot still slipes out. Those sticky pads have removed some of the logo from insoles, it's not from wear). * Lightweight linen upper - versatile and breathable * Rust-proof eyelets and genuine rawhide laces with barrel ties, for easy on/off and a secure fit * Moisture-wicking dri-lex material keeps feet cool and dry * Memory foam insoles provide comfort and arch support * Non-marking rubber outsoles won't scuff floors but gives you sure footing, from the beach to boardwalk
