Title:
EXPANDING SHOE (MID-SOLE/OUT-SOLE)
Document Type and Number:
WIPO Patent Application WO/2023/091028
Kind Code:
A1
Abstract:
A shoe that expands as the foot grows to reduce the amount of footwear that a child requires as he/she grows to alleviate the financial strain that a family faces when raising a child. As the foot grows the out-sole and mid-sole will open up in a similar fashion to a rose as it flowers, the wings on the out-sole and mid-sole will roll down and open up as the foot grows. The out-sole and mid-sole are offset so that as the foot grows and the shoe expands, only the mid-sole and out-sole will come into contact with the ground thus protecting the upper/foot. A durable upper will be used with elastic areas strategically placed to accommodate the expansion as the foot grows. A lacing system will be used to secure the foot on place and will be loosened as necessary while the foot grows.

Description:
Expanding Shoe (Mid-sole/Out-sole)

Description:

A shoe that expands as the foot grows to reduce the amount of footwear that a child requires as he/she grows to alleviate the financial strain that a family faces when raising a child. This is not only a cost-efficient design, it is also sustainable as children's shoes are often discarded before they are fully worn out due to their feet growing at such a rapid rate. It is not uncommon for children in lower class families to continue wearing shoes that are too small as they cannot afford to buy a new larger pair, this design will decrease the amount of podiatric issues that can form/continue into adulthood associated with wearing improper fitting footwear as a child. As the foot grows the out-sole and mid-sole will open up in a similar fashon to a rose as it flowers, the wings on the out-sole and mid-sole will roll down and open up as the foot grows. The out-sole and mid-sole are offset so that as the foot grows and the shoe expands, only the mid-sole and out-sole will come into contact with the ground thus protecting the upper/foot. A durable upper will be used with elastic areas strategically placed to accommodate the expansion as the foot grows. A lacing system will be used to secure the foot on place and will be loosened as necessary while the foot grows.
