The Spenco Men’s Sport Cushion Insole is designed for people who experience muscle fatigue in the feet or legs due to participating in a range of athletic or daily activities such as jogging, running, walking, playing sports or exercising, especially on hard surfaces. It was built with industry leading Polysorb® structured foam which provides premium heel-to-toe support and takes comfort to the next level. The heel pad construction offers increased shock absorption and heel strike protection, and the top cover reduces pressure at forefoot. This insole is designed for use in a variety of shoes, including athletic, work and most casual styles. The Spenco Trim-To-Fit Sport Cushion insole is intended to fit men’s shoe sizes 7-13 and may be trimmed as needed for a true custom fit. To trim, simply remove the existing insole from your shoe, line it up with your new Spenco Plantar Fascia insole as a guide and trace with a ballpoint pen. Carefully cut with a sharp pair of scissors, then insert into your shoe with the top side up.
