“The Sigma is a strong first entry into the performance distance running category. It’s a well-designed shoe offering an alternative to mainstream options. Its strengths are in its blend of stability, responsive cushioning, and a snappy-yet-forgiving plate implementation. I think it is an excellent choice for runners seeking a versatile trainer/racer that can handle daily miles but truly comes alive when the pace quickens.”

“I tested the Sigma on the HYROX course in New York City and it outperformed any shoe that I’ve ever worn. I’ve completed over 25 HYROX events, and no shoe has been as fast as the Sigma. The stability is unmatched for lunges and wall balls and the grip is excellent on the new turf.”

“Speedy and grippy, great energy return!”

“A smooth ride… comfortable, breathable, and lightweight”

“Any type of runner or Crossfit Athlete would benefit from the Sigma.”

“Great for someone looking for a lower drop shoe that can run at faster paces.”

“A great all round running shoe especially for those in the hybrid space. A good mix of speed and stability for station work.”

“Really good ground feel with decent energy return. Grip was good. I think this shoe could be used as a strength builder. Not just for mileage, but for your intrinsic foot muscles. Great for someone wanting to build mileage.”
