Product Condition: These served me well this summer in the sea and rivers. However, there was a problem when climbing a large weir in a nearby river. The metal parts of the spikes got in the way and I couldn't climb without slipping, so I switched back to radial soles. Instead, they were exceptionally good on river moss, so I enjoyed walking underwater this year and got hooked on it. Product Information: Quoted from the manufacturer's website: https://www.x-sell.net/shang-pin-risuto/%E9%AE%8E%E3%82%BF%E3%83%93-(%E4%B8%AD%E4%B8%B8)-(%E3%83%95%E3%82%A7%E3%83%AB%E3%83%88%E3%82%B9%E3%83%91%E3%82%A4%E3%82%AF%E3%82%BD%E3%83%BC%E3%83%AB%EF%BC%89/fp-5783 These are the Nakimaru type, which offer high freedom of movement for the toes and are easy to walk in and wear. They have an adjustment belt to reduce bulkiness on the inside. They have a side zipper for easy on and off. They use a YKK zipper that opens and closes smoothly. They have a kick-off for easy removal. They feature toe guards for increased strength. They employ a comfortable water drainage system to drain water from the soles. Especially in places with fast currents and unstable footing, the felt spike sole specification allows you to firmly grip with the effect of the spikes.
