I'm selling these because I bought new ones. I used these for about 4 years on rocky shores, streams, and lakes, while replacing the soles. The included soles (US9) are VIBRAM IDROGRIP. These are also recommended for those who already own Korkers wading shoes and just want the soles. Wading Shoes Korkers TERROR RIDGE Sizes US9 (27cm) Boot Weight (US9, one shoe) 650g Included Sole VIBRAM IDROGRIP OmniTrax - OmniTrax Interchangeable Sole System allows you to get the right traction for the situation. Closure System - Combines traditional shoelaces with durable hardware and a dynamic heel lock mechanism for a great fit. Fast Drying - Uses water-repellent materials to shorten drying time. Also prevents the spread of unwanted aquatic organisms. Durability - Synthetic uppers, more durable and abrasion-resistant than genuine leather, combined with PU reinforcement panels and a molded TPU toe cap. Comfort - Features Achilles reinforcement pads that stabilize the foot and provide comfortable support. Internal Drainage - Water that enters is drained through channels inside the boot to openings in the midsole, keeping your feet light even when you get out of the water.
