Not recommended for beginners. The Shenxingzhe SE 2nd gen pairs a full-length carbon fiber plate with a Duowei PEBA supercritical foam midsole in an advanced racing build. Its 28/34mm stack with a low 6mm drop is racing geometry, and the plate's rigid propulsion demands a solid gait and plenty of leg strength. Without that strength, the plate alters natural foot mechanics and increases load on the plantar fascia and calves. Build six months or more of base with a cushioned trainer and 100km+ monthly mileage before considering a carbon racer.
