The dynamic upper material expands longitudinally during toe-off, reducing fabric strain, best running of all time.

The SONICBLAST shoe offers a lightweight and responsive ride that makes it functional for tempo runs and your daily training.

The midsole features a two-layered foam with FF BLAST MAX and FF TURBO cushioning to help create a lightweight, bouncy, and advanced cushioning running experience.

Additionally, an ASTROPLATE propulsion mechanism is centered in the foam. This helps propel your momentum forward, creating a faster feel underfoot.

Designed ForNeutral/Underpronation

Neutral

• Foot Type

  Normal size arches

• Push Off

  There is even distribution from the front of the foot.

• Considered Injuries

  Less likely due to effective shock absorption, but neutral runners are not immune to injury.

• How your foot contacts the ground

  The foot lands on outside of the heel, then rolls inward (pronates) to absorb shock and support body weight.

Underpronation

• Foot Type

  High arches

• Push Off

  The pressure is on smaller toes on outside of foot.

• Considered Injuries

  Plantar fasciitis, shin splints, ankle strain.

• How your foot contacts the ground

  The outer side of the heel hits the ground at an increased angle with little or no normal pronation, causing a large transmission of shock through the lower leg.

A gusseted tongue design prevents shifting and improves overall comfort by eliminating pressure points, balance running shoes.
