Footwear company Keen is celebrating the 15th anniversary of the company’s Newport sandal with a party Saturday, April 14, at REI Denver from 10 a.m. to 4 p.m.

The event will include a band, food carts, balloon animals and punch cards with prizes and free swag. More details can be found by visiting this website.

The event is meant to commemorate the 15th anniversary of Keen showing up at its first Outdoor Retailer Winter Market tradeshow with one shoe, the original Newport, a summer sandal featuring show-stopping looks with hybrid performance and unlike anything anyone had seen before.

Fifteen years later, Keen commemorates the original Newport sandal by launching a collection that celebrates an environmentally-friendly future and pays homage to past fan-favorites Newport Eco, Newport Hydro, Newport Retro Hemp and Newport Retro Tie-Dye.
