Shimano Rockshore Wet Boots - 28.0cm - Cut Rubber Pin Felt

Rockshore Wet Boots (Water Drain Pin Felt [FS-080U] 28.0cm

These are rockshore shoes with felt spikes, purchased new from Mercari Shop last week and used for about half a day.

I bought them a size larger with the intention of wearing waterproof socks or wet gaiters, but even with both included insoles inserted, they were too big.

For reference, my actual foot size is 26cm. For New Balance, Adidas, and Converse All-Stars, I wear 27.5cm, and for Nike, it's either 27cm or 27.5cm depending on the model.
When I tried on Shimano's Geo-Lock Game Shoes, 27.5cm felt about right.

After use, I immediately rinsed them thoroughly with lukewarm water to remove salt upon returning home, and washed them with diluted neutral detergent.
When I lightly brushed them, the surface of the adhesive at the junction of the rubber and neoprene became rough and whitish, so I touched it up with Some Q (a fabric dye/paint). However, I don't think this will cause any particular issues with use.
