Alpen launches RS_#002 running shoes with supercritical foam technology

Alpen Co., Ltd. has announced the release of its second running shoe series, the RS_#002, under its ALPEN RUN community brand. Scheduled for release on October 23, 2026, the shoe focuses on a combination of lightness and responsiveness to help runners improve their personal bests.

The RS_#002 features advanced supercritical foam sole technology, utilizing nitrogen or carbon dioxide under high pressure to create a highly uniform A-TPU material. This technology achieves a density half that of traditional EVA material while providing 1.7 times the rebound and cushioning coefficients.

Additionally, the shoe incorporates the KaRVO™ shank, a lightweight material developed by Dayatex, designed to maintain stability and form during the latter stages of a race. The design is based on anatomical data from 12,000 Japanese runners to ensure an optimal fit for those targeting sub-3.5 to 4-hour marathon times.
