Advanced technologies for modelling and production are an important part in the whole process of product manufacturing. These advancements have changed the way of product development and play an important role in customization. In the footwear industry, as in any other industry, the use of these technologies is widely spread. Footwear comfort is one of the main selection criteria for purchase. Considering this fact, a case study of different steps for shoe designing according to individual foot shape will be presented. Taking into consideration the aesthetics of the sole and in a more sustainable view, through topological optimization reducing of material wastage for sole production will be presented. By means of the topological optimization in the shoe design process, sole optimization is realized. As a part of personalization, feet’s plantar pressure maps taken from 1 participant gave a better explanation of weight distribution of each foot. Following, sole personalization according the plantar pressure maps for each foot gives the possibility to obtain the best least material design according to the feet’s pressure while maintaining biomechanical performance.

Every year, an average of 1000000 L of mineral water are sold in Portugal. An amount of plastic waste from the bottles, plastic and labels could arise ecological problems. Portuguese are now paying more attention to environmental issues and most consumers consider sustainable issues in their purchase intentions. This study analyses how sustainable Portuguese water bottles considering two important functions of packages: technical analysis (material usage for plastic bottle, plastic cap, label and complete amount of water) and communication role (how consumers perceived the bottle in terms of sustainability). Therefore, two studies are carried out. The first measures the weight variations of bottle components and the second inquiries the consumers to rank the bottle pictures in terms of sustainable design attributes.
