We started with the traditional best-selling 301 single layer construction, selected a higher quality, thicker, softer and more durable leather for the top sole and strap. The antiqued surface of the top sole is uniquely distressed giving each pair its own unique story. The top sole has an oil, paraffin and water based waxing process giving it the luxurious finished look and ultra-soft feel. The double 1/3” narrow straps are made with luxury leather is rolled and sewn to a 2,000lb military grade nylon, straps are held together by a soft nylon toe piece using our signature box X toe construction and featuring the original Rainbow woven label. Holding things together we use a waxed, bonded nylon thread that will not fray or pull out. Each layer is triple glued with Sparky’s uniquely formulated and patented glue. The left sandal is embossed with the Rainbow Sandals logo and the right sandal proudly displays the Jay “Sparky” Longley signature. The Sandpiper is of course backed by the Rainbow Sandals Lifetime Guarantee.
