Children health and safety are key aspects for parents. One of the main concerns of parents is the correct motor development of their children, which involves different aspects depending on the age of the child. For infants, the acquisition and improvement of gait is the most relevant issue, while for older children the quantification of the type and quantity of physical activity to avoid obesity becomes the key aspect. Parents frequently have uncertainty about if their child is achieving the developmental milestones expected at each moment of growth, for example if the child crawls, stands alone or runs enough time, etc. International Shoes Garvalín S.L. (hereinafter Garvalín), member of Garvalín Group, is a Spanish company created in 1988, focused on manufacturing footwear for children. We are developing a new line of products named Biomecanics®, specially designed for the different developmental stages of children. The new strategic approach of Garvalín is to extend the user-oriented scope of Biomecanics® line of children footwear beyond the product design. Therefore, Garvalín’s overall objective with the present project is to create a new line of disruptive sensorized footwear (named BIOsenSHOES line) based on Biomecanics® line, able to monitor biomechanics and activity of the children at the different developmental stages, and to provide parents with information supported by experts through a novel app for smartphones and tablets. Children footwear is a mature high volume market accounting for 15-20% of total footwear sales, which are annually estimated at 300 million pairs and value of around €7.5 billion in the EU, and is expected to grow at a CAGR of 3.7% to 2018. BIOsenSHOES potential market accounts for 102 million children in Europe, which is Garvalín’s main market (75% of our sales) and 44 million children in US, our second largest market (12%).
