Feel as good as you look in the KEEN Sisters MJ skimmer. This women"s mary-jane casual shoe is made from durable nubuck and lined in rich, premium leather for breathability; the adjustable buckle strap ensures a snug fit, while the full grain leather overlays add rich detail. Underfoot, the KEEN.CUSH insole is made of recycled polyurethane, cork and memory foam for support that molds to the unique shape of your foot; it can be replaced with an orthotic, delivering even greater personalization to the KEEN Sisters Mary Jane casual shoe. A non-marking rubber sole provides dependable traction, wherever your busy day takes you. Fit tip: This shoe runs a half-size short. KEEN recommends ordering a half-size up from your normal size (if you normally wear an 8, order an 8.5).
