Sof Sole traces its origins to 1991, when Implus introduced the brand as a line of sports-specific performance insoles. The goal was to provide athletes and everyday users with improved comfort, cushioning, and support without requiring custom orthotics.

Originally focused solely on insoles, the brand gradually expanded into additional footwear accessory categories. By the early 2000s, Sof Sole had added:

• Shoe cleaning and maintenance products
• Waterproofing treatments
• Shoe deodorizers
• Athletic and casual socks
• Replacement shoelaces
• Heel liners and fit accessories
• Cleats and traction products

Today, Sof Sole products are distributed internationally and are designed for both athletic performance and everyday comfort. 2

Sof Sole’s mission is to help people customize their footwear for improved comfort, support, and performance. The company emphasizes that footwear should adapt to different activities—from daily commuting and standing at work to running, hiking, and competitive sports.

Its products are designed to reduce foot fatigue, improve fit, absorb shock, and enhance the overall wearing experience. The brand’s marketing slogan has often been “The Sole of Performance.” 3
