Redleyfins Bodyboard Fins, Size M, Soft

Thank you for looking.
This is a size M Redleyfins, which was extremely popular and is no longer in production.
I usually wear a size S, but I had one size up for thick winter socks.
Since I no longer go into the ocean in the dead of winter, I'm listing it in case someone is looking for it.

I purchased this over 10 years ago, so there will be some signs of wear and tear, but it still has elasticity and should be usable.

This is a used item, so please understand and purchase carefully with no claims or returns.

- Brand: Redleyfins
- Size: M
- Hardness: Soft
- Color: Blue, Green, Yellow

Sizing is for reference only.
I believe it would be a good fit for someone around 25.5-26 cm.
My size:
I use REDLEY in size S.
My feet are wide and high, 24 cm.
For regular shoes, even size 25 cm might not fit if they are narrow, but for wide shoes, I can sometimes wear size 23.5 cm.
When wearing 5mm winter socks, the M size felt a little loose.
