I have a pair of breathable waders and the boots. They work great but this time of year they are to hot. (At least they are for a big guy like myself LOL). So I bought a pair of neoprene booties from little river outfitters. They are basically the neoprene stocking part of the wader. They have the gravel gaurd and allow me to use my felt sole wading boots year round. Which makes that particular investment a little easier to justify. And I've had all the knee surgeries I ever want and love the felt soles. The streams I fish are literally covered with slick rocks on bottom. Little River Outfitters are top notch in my honest opinion and offer free shipping, but I'm sure some of our sponsors probably carry the neoprene booties as well. They are made by Simms.

Hope that helps,
