can anyone recommend a shoe that will work for both cycling and aerobic activity?
It depends on many things. Your style, preference, type intensity, Cross-trainers might be better (and less expensive) than buying a number of activity-specific shoes.and tend to have a wider outsole, lateral support all over (for activities that take place in directions other than forward motion) and additional support for the heels and legs. So considering all that my tree top choices are: Avia Avi-Maximus, Puma BioWeb Elite, Nike Free TR
