Unlike flimsy foam inserts, these Vionic orthotics utilize a hardened plastic shell paired with EVA material to provide serious motion control. I found the three-zone comfort technology particularly effective for managing the impact of fast walking or running, thanks to the specialized shock dot in the heel. The built-in 4-degree rear foot wedge works hard to combat excessive pronation, which is a game-changer for anyone dealing with the discomfort of flat feet or plantar fasciitis. Because they are contoured for 100% foot contact and feature an odor-absorbing cover, they feel like a professional, podiatrist-designed upgrade to your standard footwear rather than just a temporary cushion.

Because they use a strong self-adhesive material, I didn't experience any of that annoying shedding or slipping throughout a full day of walking.
