One of the major goals for citizen runners is to complete a full marathon in less than four hours. Known as "sub-4," this is a prestigious title that only the top 20% of runners can achieve.
ASICS has developed the "S4" for runners aiming for the sub-4 mark.
S4 22,000 yen
Pre-sale at ASICS Online Store from February 16
The two-layer midsole features our proprietary "FF BLAST TURBO" foam. It deforms and compresses at the moment of landing, and quickly returns to its original shape, naturally extending the stride.
Inside, a carbon plate is added in a V-shape, sloping down from the toe. While improving stability, the user can enjoy the resilience that only carbon can provide.
The upper is a lightweight and breathable "Motion Wrap Upper" and the outsole is equipped with "ASICS Grip". The comfortable ride will lead you to sub-4 achievement.
In addition, the insole, which uses "Solution Dye," a dyeing technology that colors the raw material itself, is a nice touch that significantly reduces CO2 emissions, an eco-friendly consideration.
While inheriting the lineage of the high-end METASPEED series, this remarkable model has been rearranged in many places to achieve sub-4. If you are serious about sub-4, it is well worth choosing.
