It’s not even one year old the start-up launched by Alessandra Antonetti, an architect born in Lecce in 1986 who has found a solution to the problem of sweaty feet in the summer and icy ones in the winter. Her idea is called Aria and is a smart sole that uses patented technology to adjust its temperature automatically, maintaining a constant level of comfort. The sensors built into the sole do not limit themselves to controlling this aspect: they keep track of the number of steps you take and the calories you burn and check your posture. The data can be shared through your smartphone with your doctor or personal trainer.Aria, a smart sole designed by Alessandra Antonetti.

Combining three biomechanical sensors with a sophisticated algorithm, it tracks biomedical parameters and performance data and communicates them instantaneously through earphones. This virtual trainer, the idea of Andrea Rinaldo, a former professional swimmer that was initially launched with a crowdfunding campaign and then entered into production, costs from 200 to 300 euros, depending on the model.XMetrics, from an idea by Andrea Rinaldo.
