Hyogo / KobeUpdated 6/18/2026

Seiwa Co., Ltd., founded in 1960 in Kobe's Nagata district — Japan's traditional footwear hub — operates the PRETAflex brand from an in-house production line. The company developed a proprietary institch construction that bonds uppers and soles through stitching without organic solvents, enabling eco-conscious production. Skilled craftspeople with 30+ years of shoe-making experience hand-stitch the moccasin uppers and hand-finish every pair, yielding a lightweight (approx. 180g per women's shoe) and supple feel. With over 140,000 pairs sold through department store pop-ups and its own EC, PRETAflex unites 'Made in Japan, genuine leather, comfort, and environmental care' into one brand story — making it an ideal OEM partner for high-value women's leather shoes and moccasins.
