Hub, the Dutch footwear brand, has introduced a new three-layer insole, intended to stimulate blood circulation, which is generally used in running shoes, for its spring/ summer 2015 collection. Hub's production partner in Vietnam, who now takes care of the complete production of the Dutch brand, produces the new insole. Previously, the production was handled partly in China and Vietnam. A production partner in Portugal makes the fashion line, which is currently selling very well. Hub had previously introduced a new outsole in the men's shoes offered for the autumn/winter 2014/15 season.
