Socks with an U-shaped 3D discharge element are capable to reduce dynamic plantar pressures under the central forefoot.

Cushioning for the central and plantar zone of the forefoot, integrated into the body of the sock, could reduce excess pressures in that zone. The objective of this study was to verify the capacity of a sock with a cushioning element to reduce forefoot plantar pressures relative to the same sock model without that element. Dynamic plantar pressures were measured in a sample of 38 participants (25 women and 13 men) using the FootScan plate system following the two-step protocol. Measurements were made in three situations selected at random - barefoot, wearing control socks, and wearing the experimental cushioned socks. Maximum pressures were analysed in seven zones of the forefoot (hallux, lesser toes, and 1st to 5th metatarsal heads). The zone of greatest plantar pressure was in all situations located under the 3rd metatarsal head. The pressure was lower (p = 0.009) under the 2nd metatarsal head with the experimental sock (10.2 ± 3.1 N/cm
