What is Bunion ?

A bunion is the prominence of the inner portion of the joint of the big toe because of poor foot mechanics. Bunions are usually caused by existing foot deformity - Flat Foot or Overpronation. 


Shapecrunch creates custom orthotics or insoles for shoes with 3D printing technology by using the biomechanics of the patient to make the arching foot back to normal, and prevent further worsening of joint of the big toe, because Bunion is a progressive deformity, which gets worse over time. 


A bunion is most likely to develop when susceptible feet are repeatedly squeezed into narrow, pointed-toe footwear. The big toe pushes against the other toes, sometimes diving over or under them. 

Shoes with narrow toes can trigger a bunion, but they're not the underlying cause. Bunions run in families, because foot type (shape and structure) is hereditary, and some types are more prone to bunions than others. Low arches, flat feet, and loose joints and tendons all increase the risk. The shape of the metatarsal head (the top of the first metatarsal bone) also makes a difference: if it's too round, the joint is less stable and more likely to deform when squeezed into shoes with narrow toes.

High heels can exacerbate the problem because they tip the body's weight forward, forcing the toes into the front of the shoe. This may help to explain why bunions are 10 times more common in women than in men.

People in occupations such as teaching and nursing, which involve a lot of standing and walking, are susceptible to bunions.

How Shapecrunch's Custom Insoles and Sandals provide the best Bunions treatment?

Bunions which are medically termed as Hallux Valgus are treated by providing proper arch support to the foot through customized insoles or custom orthotics. Shapecrunch creates customized insoles with 3D printing technology by using the biomechanics of the patient to make the foot normal. In addition to the insoles, heel cups are used to correct the pronation angle of the patient. Medial wedging aims at distributing the weight of the body and offloading the area. Custom orthotics help in relieving the pain caused by flat feet in the ankle and the knees. Also, toe separator with insoles work as a perfect combination for the treatment of bunions.

Flat Feet

The appearance and quality of this leather sandal is exceptional. From the stitching on the straps and soft touch natural leather on the footbed, the sandal is not only luxurious but would pair well with a variety of bottoms from casual cargo shorts to khaki pants. I got these because of the customized arch support; since I have flat feet, most sandals leave me with achy feet and a backache by day’s end. In just a week of wearing they have molded to my feet and all the pain gone and thanks to shape crunch team for developing such a beautiful product and ordering is very much easy  just go to application and click some pictures
