When Sportful designers created the R&D sock, they had their sights set on developing the softest and most comfortable sock they could produce. Meryl Skinlife bacteriostatic yarn is combed through to produce a sock whose exterior is incredibly soft to the touch. Skinlife is a microfiber with hypoallergenic and bacteriostatic properties that thwart both odors and bacteria commonly found in foot perspiration.
The top of the instep has an aerated web mesh pattern for ventilation while the entire bottom sole has and added thin layer of material to prevent hotspots. There is an elastic instep compression band that aids in both fit and circulation. The R&D is hand made in Italy and easily one of our favorite summer socks.
