Main Characteristics

The insoles utilize small wireless, battery-powered devices called "Pods". These are steel encased vibration motors and inertial sensors that are attached to Lechal shoes or inserted into insoles. After pairing the Pods with a smartphone through Bluetooth 4.0, they offer vibrational feedback based on the GPS directions received from the device. The Pods can be charged via Lechal's docking stations.[7]

Public & Media Impact and Presentation

While we found no review for Lechal, there are some news pieces that we analysed for any preliminary appraisal of the device.

Gizmag technology magazine informed about the device in February 2014.[11] The article summarises the key points about the device but gives no appraisal. The PSFK magazine also informs about the features but further states that the device may be a "dramatic improvement (for) disabled people" and expands on the possibilities of the device with saying that the "users can tag destinations by tapping their feet, share their route with friends, set fitness milestones and track their daily activity. They are a wearable that can be used by anyone but which includes features which make them accessible to the visually impaired." There is no specific appraisal given, but the tone of the article seems positive.[12]

APN News website informs about the launch of the device. The piece describes the device idea briefly and then mentions the Lechal initiative. The initiative means that every purchase of the Lechal Special Edition subsides a pair of Lechal shoes for the visually impaired. The initiative is done in cooperation with the L V Prasad Eye Institute. The article describes the device as user-friendly and praises the hands-free nature of it.[3]

Xing Magazine run an interviews with the co-founder Krispian Lawrence in January 2016. Mr. Lawrence said that he did not want Lechal to be seen as a wearable product first, because there was already too many wearables on the market. He also expressed that the company was overwhelmed by the amount of pre-orders the company received[13]
