Product Name: Caravan CARAVAN Outdoor Sawanobori Shoes KR 3XF WIDE Felt Sole Purchased in July of this year, used once for a half-day, 5km stream fishing trip. Although the dirt is noticeable, I lightly rinsed them with water and dried them in the shade, as I believe washing them vigorously with detergent would shorten their lifespan. There are no tears, frays, or damage. Since they've only been used once, the soles are still in good condition, and with about 10 fishing trips a year, I think they can last for another 4 seasons. They're expensive new, so how about trying them out? I usually wear sneakers size 28 or 27.5. They fit with room to spare. They also seem to fit over sock waders. Since you can adjust the laces tightly, I think they're best for those with sneaker sizes of 27.5-28.5. This model uses a 3E WIDE last, which is wider than the 3E last, making it comfortable for those with wider feet. This product is designed not only for stream climbing but also for fishing, with hooks on two points around the opening. This allows for quick adjustment of the shoelaces when you want to loosen the ankle area while crouching. The upper has a high proportion of synthetic leather to improve durability, and the easily damaged toe area is reinforced with a toe guard.
