Based on the original Classic mold, the Diamond is formed of a more flexible compound, with a flexible twist: a stabilization structure on its underside that allows more side-to-side flexion than our other Lifetime-Warranty supports. The Diamond is named for this distinctive diamond-shaped “Stability Web” pattern you’ll find on the bottom of the support. Though the Diamond was designed for the customer who needs more flexible support, the Diamond is no push-over. Backed by Good Feet’s Exclusive Lifetime Warranty, the Diamond is guaranteed to never flatten, crack or break, no matter how hard you work while wearing it.
Flexibility: Medium-Flexible
The diamond-shaped Stability Web pattern on the underside of the Diamond empowers it to follow the side-to-side motions of the foot during gait. The Diamond can gently accommodate the gait of flatter or more sensitive feet, while still providing enough stability to help put the foot in the Ideal Foot position.
Though flexible, the Diamond is firm enough to support all four arches of the foot. Its flexibility makes it a perfect companion for tighter-fitting dress shoes, or other activities that require the alignment of an Exerciser with less aggressive gait control.
What’s in a Diamond?
“Stability Web”
The underside of the Diamond features a pattern of connected “diamonds,” which we call a “Stability Web.” These webbed diamonds are positioned under the forefoot of the support, to provide stability during gait.
What Does It Do, And How Can It Help?
The Diamond’s Stability Web pattern is engineered to provide support to the forefoot without making the Diamond too rigid. Each diamond-shaped stabilizer flexes slightly with each step, creating a gentle ride during gait. The most flexible support in the Exerciser family, the Diamond is most suitable for those with flatter, more sensitive feet.
Metatarsal Rise
The “front” end of the Diamond features what looks like a miniature pitcher’s mound. This is called the “metatarsal rise,” and it is particularly effective at taking pressure off the ball of the foot, the toes, and the heel.
What Does It Do, And How Can It Help?
By properly supporting the metatarsal arch, the metatarsal rise lifts up the bones in the ball of the foot, effectively preventing them from hitting the ground too hard every time the foot pushes off for a step. This means that the metatarsal rise in the Diamond can help relieve pain caused by pressure in the ball of the foot, and also distribute body weight away from corns, calluses, and other painful problems. The Diamond’s metatarsal rise works as part of its flexible support structure to gently support the front of the foot without the aggressive realignment provided by firmer members of the Exerciser family.
As it takes pressure off the ball of the foot, the metatarsal rise in the Diamond also fans out the bones that form the arch and the top of the foot. At the same time, the toes are relieved of lots of pressure. This is why the Diamond can help prevent the toes from gripping the ground with each step, which could be the cause of hammertoes, calluses or corns.
While properly distributing pressure through the front end of the foot, the Diamond’s metatarsal rise also redistributes pressure through the whole bottom of the foot, effectively reducing strain on the plantar fascia ligament (a band of tissue that runs from the bottom of the heel to the ball of the foot). When the plantar fascia ligament is allowed to stretch under too much pressure, it can become inflamed, causing a condition called “Plantar fasciitis.” Because the Diamond’s metatarsal rise is so effective at properly distributing body weight through the foot, it can greatly reduce strain on the plantar fascia ligament. While other supports may be too rigid and aggressive for those with flatter or more sensitive feet, the Diamond has helped many Good Feet customers find relief from their Plantar Fasciitis pain.
Heel Cup
The heel cup is a cup-like indentation at the heel end of the Diamond. It is designed to gather the fat pad beneath the heel and to help absorb the “step shock” that courses through the body every time each heel strikes the ground.
What Does It Do, And How Can It Help?
Every step each foot takes begins when the heel makes contact with the ground, in what is called “heel strike.” When the heel strikes the ground, up to three times the body’s weight can be exerted on the bones and tissues of the heel. This puts the heel under tons of stress, especially if it is not properly supported. The Diamond’s heel cup is designed to help cushion and properly align the heel, thereby reducing the stress of each step.
A stable heel is the foundation of a stable body. If a heel is striking the ground at an angle, or rolling too much to one side during gait, it can cause imbalances throughout the entire foot, ankle, knees, and eventually through the entire body. By supporting the heel, the Diamond can help align each step, starting with heel strike.
While ensuring that each heel strike is balanced and cushioned, the Diamond’s heel cup can reduce fatigue on the ankles, knees, hips, and back. A properly supported heel can more properly distribute the weight of the body through the legs during gait, which means that the tendons of the ankles and knees won’t have to work extra hard to keep the body upright. As part of an arch support system, the Diamond can be the first step toward an ideally aligned skeleton.
Inner And Outer Longitudinal Arch Support
The Diamond also features support for the inner and outer arches of the feet. These are designed to stabilize the foot during gait, to help prevent it rolling inward or outward with each step.
What Does It Do, And How Does It Help?
By supporting all four arches of the foot, the Diamond helps to properly distribute pressure through the entire foot, thereby preventing any one part of the foot from taking on too much pressure. This can help alleviate pain in areas of the foot that are straining under too much stress.
The Diamond’s inner and outer longitudinal arches stabilize the foot during gait, helping to prevent pronation and supination (rolling inward or outward). By stabilizing the foot, the Diamond helps to promote proper gait, thereby reducing excess stress in the ankles, knees and hips.
As part of a complete Good Feet Arch Support System, the Diamond is ideal for:
- Walking
Weightlifting
Working (boots, shoes, etc.)
Standing all day
Non-running exercise
