I am now wearing Merrell low-cut Radius shoes - they fit very well but are no longer made. Are the "Radland" shoes the new version? Does anyone have experience with the "Radland"? My feet are very hard to fit so I would rather stick with Merrell. I also cannot tolerate a boot or mid-cut (sensitive ankle problem) -- it has to be low cut. It does not matter to me if they are waterproof or not.
