X-Dimension Golf Shoes

Kuraray Co., Ltd. has developed a new man-made leather, SOFRINA-a, which offers luxurious feel, durability, and softness approaching that of natural leather. As a result, shoes made with SOFRINA-a are highly praised for comfort. Acushnet Japan, Inc. selected this new material for its new FootJoy X-dimension series golf shoes, which will be introduced in March. (The series will initially include models no. 53176, 53187, and 53195.)

SOFRINA-a is made of two fibers of different thicknesses. Kuraray employed its proprietary non-woven fabric technology to intertwine nylon fiber and nylon microfiber (0.07dtex and 0.0001dtex) using a three-dimensional intertwining process. Use of a 0.0001dtex microfiber produces a high-density non-woven fabric with a uniform degree of stretch regardless of the orientation of stress. An addition, these non-woven fabrics are reinforced with special polyurethane resin, which gives SOFRINA-a a satisfying feel on a par with natural leather. This also makes for improved workability during the shoemaking process, and a better fitting shoe.

FootJoy puts emphasis on providing golf shoes that give golfers the comfort, support, and sure footing they need. The new X-dimension series shoes have an original, athletic design, and the use of SOFRINA-a for the upper allows an improved feel and fit. The X-dimension series shoes also have the "X-Stability Bridge" sole, which provides support to prevent rolling the foot during the swing. SOFRINA-a is a perfect match for the FootJoy brand, with its emphasis on comfort and fit.

Kuraray plans to market SOFRINA-a not only to the shoe industry, but also for applications in clothing, interior furnishings, car seat upholstery, industrial materials, sundries, and a wide spectrum of other markets. Kuraray continues to make advances in non-woven fabrics and processing technologies, and will continue to develop products that meet the needs of the market.

Characteristics of SOFRINA-a

(1) Look and feel on a par with natural leather
  • The use of non-woven fabrics made of nylon fiber and nylon microfiber (0.07dtex and 0.0001dtex) and three-dimensional intertwining lamination gives this material minimal directionality and well balanced stretch characteristics, while the special polyurethane resin reinforcer gives it a substantial feel.
  • Special surface finishing technology makes for an appearance and beauty approaching that of natural leather.
(2) Excellent surface properties and water resistance
The use of a special polyurethane resin and special surface finishing technology give it improved abrasion resistance, exfoliation resistance, and water resistance.
(3) Soft feel
Flexibility was achieved through the use of nylon fiber and microfiber non-woven fabrics, and a soft feel results from the use of thin-film surface technology.
(4) Light weight
Its weight is approximately 70% that of natural leather.
(5) Easy to care for
Dirt wipes away with a wet cloth.
