Gamakatsu G-Spec Felt Spike Shoes (Power Type) GM4550 Used once for a fishing trip on offshore rocks. * Approximately 6 hours. Washed with water on the same day after the trip. The insoles were not used as I used different ones. If you wish, I will include the box. I am very satisfied with the quality, but they were a little tight, so I am selling them to buy a new pair.
