Technology under your Feet


1) Cork Midsoles


Cork soles are normally bonded with resin for increased durability. Insoles made from the material offer an anatomically-correct footbed, offering numerous pain-relieving and comfort benefits.

1.1) Form-Fitting

 Cork is a relatively soft material that is densely compacted for shoe use. However, when subjected to the weight and heat applied though normal wear, cork insoles mold themselves to the wearer's foot. This creates a custom fit that conforms to the wearer's natural shape, offering a high degree of comfort. Despite its ability to mold to a certain degree, the material stays firm compared to rubber or artificial insoles, maintaining proper arch support and foot alignment. The mid sole has contours to support each part of your feet these contours are responsible for all the comfort for the feet.

1.2) Odor Resistance

Cork is a moisture-wicking material. Bacteria feeds on the sweat secreted by feet when inside shoes or sandals. By using cork, there is far less moisture buildup left in the shoe, starving bacteria of food. As a result, any shoe using a cork insole will naturally be relatively odor-free just from normal use.


1.3) Impact Resistance

For those on their feet for extended periods, cork insoles and outsoles offer a degree of relief. The material's natural elasticity means less impact force is transferred up into ankles, shins and knees, reducing joint stress. The material's ability to hold the heel and foot in an orthopedically-correct position -- combined with its shock absorption capacity -- potentially reduces instances of plantar fasciitis and other forms of foot pain. For this reason, many premium shoe manufacturers and medical supply companies offer cork insoles or orthotics to reduce plantar fasciitis pain.

1.4) Naturally Renewable

Cork is harvested from cork trees, with the material forming just under the upper bark layer. Cork trees are harvested after 25 years and every nine to 13 years thereafter. The material can only be stripped between May and August to prevent tree damage. The material is recyclable, in turn used for flooring, insulation and new soles.


2) Sole Plates

Sole plates (Patented): What makes Murtle durable, versatile and unique is the sole plates. The conventional modular footwear use either velcro or Magnets to achieve interchangeability whose life reduces with time as it comes in contact with  water and dust repeatedly. The sole plates are made of ABS plastic which is highly durable and wear resistant for a very long duration. The plates employ threading mechanism which is as reliable as ISRO's rocket launch. The engineering team has considered for all the linear/ tangential and shear stress a sole plate faces and then zeroed down on all the values. We still continue to test, so that we deliver nothing but the best!
