Wiivv lets you scan with smartphone your feet to make sandals specially tailored to your measurements.
The shoes that are molded specifically for your feet are definitely comfortable and sometimes even necessary for people with orthopedic problems. Wiivv allows you to model and measure your legs by taking photos of them and by using one application for smartphone. Then uses this data to create a 3D model of your foot, and 3D print a shoe with a sole perfectly tailored for you.
The company has been offering this service for over a year now, and has now launched a campaign Kickstarter to create matching sandals.
It's the same basic idea, but instead of just making the insole, he'll be making the entire sandal. You can watch the related promo below video.
If you are interested, you can make copies of your feet and join in Kickstarter funding campaign with $ 79 for a pair of sandals or $ 150 for two pairs. The company says it will send you sandals until August of this year.
