The Delfiero bioceramic slippers guarantee a natural anti-inflammatory, pain-relieving, and regenerating function. The patented outer fabric is made of pain-relieving Resistex Bioceramic obtained from natural mineral oxides, which are added to polyester fibers, and then fused at high temperatures, remaining embedded within the fibers without dispersion. The result of this processing is a fabric capable of receiving the so-called FIR rays (far infrared rays) emitted by our body and reflecting them back towards the body itself, creating an energizing and pain-relieving therapy with significant benefits for the body. In fact, infrared rays penetrate the body up to 4/5 centimeters and act on the water contained within the cells, creating what is called healthy cellular activation. The product is made for the Delfiero Selection From entirely in Italy. Rubber sole. Available sizes: 34 (34/35), 36 (36/37), 38 (38/39), 40 (40/41), 42 (42/43), 44 (44/45). Gross weight: 190 grams.
