Get on the road in any weather.

For the second stop of the ASICS x Reigning Champ International Run Club, the GEL-CUMULUS® 21 G-TX running shoe circulates design inspiration from British Columbia’s Coast Mountains and its outdoor terrain. Engineered with a GORE-TEX™ upper, this shoe’s Glacier Grey color palette reflects the hues seen in Vancouver’s network of foggy trails that span from the shores of the Pacific Ocean to the forest in the Coast Mountains. Accented with Reigning Champ’s signature zig-zag stitching and a reflective trim to improve visibility when running during low-light excursions, the GEL-CUMULUS® 21 G-TX running shoe also incorporates FLYTEFOAM™ Propel technology in the midsole for responsive cushioning.

 

  • Attenuates shock during impact and toe-off phases, and allows movement in multiple planes as the foot transitions through the gait cycle.

  • ASICS design philosophy that employs linked componentry to enhance the foot's natural gait from heel strike to toe-off.

  • Acronym for ASICS High Abrasion Rubber. Placed in critical areas of the outsole for exceptional durability.

  • Moisture management (Ortholite is a registered trademark of ATP Manufacturing LLC).

  • Employs 45 degree full length SpevaFoam™ 45 lasting material for a soft platform feel and improved comfort.

  • ASICS energetic foam formulation that provides supreme bounce thanks to a unique elastomer compound.

  • 360-degree reflectivity for increased visibility.

  • Waterproof and breathable upper designed to protect the foot during extreme weather conditions.

If you are unsure of your shoe size, measure your feet to find your size. Please also keep in mind that each shoe brand fits differently and therefore your size may be different by brand and even be different by style within the same brand. Please refer to the fit guide and reviews on products for additional information.

Please follow the directions below:

  1. Wearing a sock of medium thickness, stand on a piece of paper.
  2. Place a mark at the end of your heel and at the tip of your longest toe.
  3. Mark the sides of your foot at the widest part.
  4. Measure both feet and use the larger of the two
  5. To find your size, use these measurements and refer to the sizing chart below.
  6. If your measurements are between two sizes, or you find one foot's measurement is larger than the other, always move up to the larger size.
