Tulip loafer by Ilse Jacobsen. This is our take on the classic college loafer. The upper construction is made without any glue and attached with a matching recycled thread. With a penny strap and rounded toe, they?re set on our iconic Tulip sole. The upper is attached to the outsole using no glue, only recycled thread. The upper material is microfiber with a glossy PU surface. Outsole: 75% natural rubber and 25% recycled rubber. Insole: 60% EVA, 40% Pigskin.
