Zspheres adaptive skin had too sharp edges

Hi!
I’m trying to make a character using zspheres and I’ve got some trouble with the adaptive skin. Some places are getting really sharp edges, especially if two spheres are close, but also the ends (like the toes) are getting flat instead of rounded.
I wonder what this may be caused by and if there is a way I might fix it?
Also I need to increase the density to 3 to get the look others sem to get at just 2, is there something I can do about that?
