  • The Vionic Sierra is an active walking trainer designed to balance style and function. It flaunts a carefully devised knit upper for breathability and flexibility. It is also made of lightweight materials.
  • A supple yet flexible EVA orthotic insert lines the bottom interiors of the shoe. This textile-covered insole is removable.
  • The shoe employs the Advanced Motion System (AMS) technology. This construction involves combining a podiatrist-designed orthotic, a lightweight upper, and a flexible and cushioned outsole. This combination of features makes the model supportive enough for everyday work, play, and other activities.

The Vionic Sierra is crafted to fit the foot dimensions and biometrics of women. It runs the full spectrum of US 5 to 11 with half sizes in between. It also has a couple of width options at hand which are B – Medium and D – Wide. The brand recommends to wear their new pair for only a few hours for the first couple of days to let the foot grow accustomed to the new orthotic comfort and support. The foot will be able to adjust within one to two weeks.

The outsole of the Vionic Sierra is engineered with a durable, dual-density rubber component that provides a steady grip on any kinds of surfaces. It is also cushioned to attenuate shock and boost comfort. It has a pliable form that promotes natural flexion.

The Vionic Sierra houses a detachable, mesh-covered EVA orthotic insert. It has a podiatrist-designed structure with additional cushioning under the toe to help improve posture and balance. It feels firm and flexible under the foot. It is one of the components of AMS, together with the textile upper and the flexible, cushioned outsole. These features work together to make the footwear supportive and comfortable.

A stretch-knitted material is what the upper of Vionic Sierra is made of. It enables the air to circulate throughout the foot chamber.

A lace-up closure locks down the foot and prevents it from moving around. It also fortifies the lateral support as the shoelaces are tightened.

A pull tab is sewn into the rearfoot area. It helps the wearer slip on the footwear easily.

The branding is displayed in two locations of this part of the footgear. One is stitched on the tongue of the model while the other one is printed on its rubber overlay.

According to the official Vionic website, this model is highly recommended by Dr. Andrew Weil, an internationally recognized pioneer in integrative medicine.
