Updates to Asics Gel Fit Sana 4

  • The Asics Gel Fit Sana 4 is developed for women who enjoy doing studio workouts or light cross-training sessions. It is fashioned to be lightweight and flexible to allow the foot to move naturally. The upper is crafted of mesh and utilizes the Mono-Sock construction to deliver a seamless, comfortable, and breathable wrap that keeps the foot supported and fresh.
  • A single unit of foam makes up both the midsole and outsole of the trainer. This singular design allows it to be lightweight and flexible to promote natural foot flexion. It is also durable and is intended to provide adequate traction on smooth floors. The heel features an additional layer of GEL which enhances the shock absorption of the midsole.

Size and fit

This women's trainer from Asics is available in US sizes 5.5 to 12 and comes only in a B - Medium width profile. This model utilizes a cleatie-like construction which aims to deliver a lockdown fit. 


The midsole of the Asics Gel Fit Sana 4 doubles as its outsole. It is engineered to be durable and grippy on gym and studio floors. The tread pattern on the underside resembles suction cups which enhance the traction, so it doesn’t easily slip during dynamic movements.


A full-length foam cushioning makes up the midsole of the Asics Gel Fit Sana 4. It is intended to attenuate shock and provide a responsive platform during workouts. The unit is also made to be flexible to promote natural foot flexion and adaptability. On top of it is a breathable textile footbed that ensures the foot chamber is aerated.

The GEL technology is present at the rearfoot. This component amplifies the shock absorption of the midsole during heel strike for a smooth heel-to-toe transition.


The Asics Gel Fit Sana 4 employs a mesh upper. This fabric is lightweight and breathable, ensuring that the inside is well-ventilated. The eyestay, which is a high-friction area, is lined with a synthetic overlay to protect it against abrasion.

The footwear utilizes the brand’s MONO-SOCK Fit System. This construction wraps the foot to deliver a snug, sock-like fit. The inside is also lined with a comfortable fabric that aim to prevent any foot discomfort.

The midfoot sports a lace-up system that allows users to adjust the fit to their liking. The sewn-in tongue is lightly padded, protecting the instep against the pressure created by the laces.

The footgear also sports a slightly plush collar that keeps the ankle area comfortable and the back of the foot locked down. A pull loop is attached at the back of the collar and assists users in putting on the shoe quickly. An overlay forms an external heel counter at the back which is designed to keep the foot steady during workouts.
