This is my wet wading footwear setup for stream fishing. I have tried everything from sandals to water shoes before settling on this system.
At the core, it consists of a pair of 2019 Simms Flats Sneakers. 2021 will be their third season and so far, after approximately 200 miles on them, they have held up well.
Coupled with the boots are a pair of Simms 2.5mm Neoprene socks and a set of gravel guards that velcro around the sock/boot. The guards really help by keeping the micro gravel out of my boot.
The Flats Sneakers are very comfortable, especially after walking over rocks, boulders and gravel all day. Not having any metal components helps alleviate any worries about rusting hardware.
The wife opted for the same boot but she went with the Simms Guide Guard sock (3.5mm Neoprene) because of the built-in gravel guards.
To date: this is the best footwear system for us. All day comfort and support! Before, we would stop about every half hour to empty painful debris from our water shoes.
