The shoe you need to check out is the Salomon Tech Amphibian. This is one of my all time favorite shoes and I have about 5 pair in my closet as we speak (or as i write, LOL). I think they are up to version 3 now, but IMO the original is still the best, although it may be hard to find. Be that as it may, version 2 is good and available as well.
Because it's a water shoe, the upper is mesh and drains quickly and then dries out fast as well. And because it's also a land shoe (hence the name), the sole is very stiff, supportive and well lugged. It's also very light weight.
I usually wear a Superfeet or gel insole OTC orthotic in mine depending on what I'm doing and haven't had any problem. So your custom orthotics should be okay, but you may need to go up one-half size like any shoe.
I wear mine for a variety of activities, international touring, light runs, biking, day-hiking and backpacking.
Check them out!
