Gone are the days of the clunky, thick-spiked golf shoes and blistering feet at the end of a round. Nike is set to release the new 2014 line of men’s and women’s Free-Inspired (FI) Footwear, which are light, spikeless and form-fitting.

These shoes, which were designed with input from LPGA star Suzann Pettersen, have an athletic design to optimize comfort and performance.

Modeled on the ever-popular Nike Free running and training shoes, the Nike FI Impact golf shoes add numerous upgrades from the standard shoe. Both men’s and ladies’ styles will be available on Aug. 1, and will sell for $160.

The outer aspect of the Nike FI Impact shoe is natural-motion engineered, which allows for the material to conform during foot movements. This aids in prolonging ground-contact time and increased energy transfer from foot to ground for a more powerful swing. According to Nike, the Integrated Traction technology of the shoes allows for a natural feel without compromising protection or stability.

The dynamic fit upper portion of the shoe has perforations to enhance breathability and ventilation — a must for those playing in the summer heat. The tongue, an often forgotten part of the shoe, has also been updated to utilize a full mesh composition for added comfort. Even with the lightweight nature of the shoe, there is still a waterproof option available.

Although skeptical at first as to the spikeless outsole, Pettersen recognized the major design potential of the FI Impact shoes saying “after I tried them once, I was dying to get them on my feet in competition.” The current No. 3-ranked golfer in the Rolex ranking system first wore these shoes at the LPGA’s LOTTE Championship in April, where she carded all four rounds in the 60s to win the tournament. With four top-10s since, Pettersen and the FI Impact shoes are making headlines.

Multiple styles and colors are available. Check out the photos below to see the available colors and styles.
