Shimano Vibram soles. These were used on 26cm Shimano Geo-Lock Rock Shore Dry Shoes. I used them for about 2 years for fishing from rafts. The shoes wore out first, so I'm selling the soles only. I've washed and dried them, but they have some dirt. In my opinion, the grooves are still present. Please check the photos. Please refrain from purchasing if you are a nervous buyer, as this is a used item. Also, please understand that cancellations and returns are not accepted after purchase. Since there is no box, I will ship them in a bag. Please be aware of this. - Brand: Shimano - Material: Rubber - Backing Material: Fabric - Design: Hexagonal Pattern - Condition: Used Thank you for looking.
