My name is Sean Chang, graduated from Feng Chia University, where I majored in Department of Industrial Engineering and Systems Management. I am keen on shoes and sneakers, so I started my career at Rich Shine International Co., Ltd., a shoe factory based in Dongguan, China after honorably discharged from military.

By working for this company and visiting various kinds of vendors over the years, I established different types of knowledge. These experiences became the cornerstone of my abilities on material, management, research and development. As my experience increased, I have the capability to organize the works from client, factory to supplier and served as a project manager and imported scheduling and management systems like Scrum and Kanban into the factory.

At this position, I believe it’s important to equipoise “client’s ideal” and “manufacture’s reality”, make the production achieves the highest benefits. From 2014 to 2019, I've led the footwear development projects of Aape (I.T Limited), NBALAB, etc., developed hundreds of models and over one million pairs were put into production. These products brought more than USD 20 million of revenue for Rich Shine.

Due to family reason, I returned to Taiwan in April 2019. Because of my passion for footwear, clothing and textile, I joined Matsumi Consultant Company, an agent of Japanese clothing brands. I work as a Marketing / PR Personnel, expand the businesses for our brands and head the media projects to enhance the reputation for them.

My retail clients including the high-end boutiques like 03 Tokyo (Bellavita), Onefifteen and Plain-Me in Taiwan. I also successfully developed the Chinese and Hong Kong market, built the businesses with 432Hz (Hong Kong), Rivets (Shanghai/Beijing) and The New Fusion (Wuhan), let our brands march into overseas market.

Both Vionic and Aetrex are brands for orthotic products; Vionic is a subsidiary of Caleres Inc., an American footwear enterprise group. They provide arch-support functions to reduce users’ pain in the trendy looking shoes.

The featured technique “VIO-NRG” of Vionic was developed from early 2015, and debuted in mid 2016. We set the arch support function on EVA midsole and made the surface of midsole 3D. After almost one year researching and testing, we found the best support area, shape and hardness. Instead of traditional insole, we took memory foam and Poron foam as midsole board to make the footbed fits users’ feet better.

Rudis contributes to wrestling culture and started their footwear projects in 2018. They provide products to youths and adults, including the signature shoe "Snyder Caliga" for Kyle Snyder, the gold medalist of Rio 2016 Olympics.

The shoes are themed on engineered knit upper, engineered mesh upper and translucent CPU outsole, combined with HF welding, heat pressing, embroidery, etc. These complex processes make our products distinguish from the wrestling shoes in the market.

Underwent a whole year testing with the athletes, we divided the upper into stretchy and non-stretchy areas for the best comfort and strength; Kyle Snyder also got a medal in his "Caliga" when he participated the 2018 World Wrestling Championships.
