I've had a hard time over the years finding a shoe large enough and comfortable enough to fit over stockingfoot waders without causing loss of circulation. The best I found was the now discontinued Teva Ricochet, an amphibious shoe, similar in style to a trail runner. It had enough toe box height and was wide enough. It was 5" at the widest part of the sole. Unfortunately my dad threw out both pairs I had. Since then I tried the Teva Sunkosi, but it was much narrower and flat. There's not enough toe box height. My toes and heels would go numb due to cold water, compression from the shoe, and water pressure. Now I'm using the 5.10 Savant a somewhat amphibious shoe designed for free runners. It's OK, but I still don't have ideal circulation. My toes still get cold in water up to 60 degrees. I don't have abnormally large feet either. I wear size 9.5-10 in street shoes, but had to go to a size 13 in the 5.10 Savant to accommodate the stockingfeet plus SmartWool mountaineer socks. I could have gone with a size 12 and had more than enough length, but the lack of width and toe box height become a problem. What are you guys wearing? I'm looking for something light and low cut. Maybe something higher cut like a dive boot as long as they don't strangle my feet. I have doubts that a dive boot would work for me since it was designed to fit over bare feet. A stockingfoot is quite bulky. Oh and no wading boots. Last year I purchased a pair of Simms Headwaters boots and the combo of fins plus boots was too heavy with my legs dangling in the water. The boots were also way too stiff for the flexing action required when kicking.
