The sidas range of conformable liners are your best bet. You can get a full foam injection option, in either stiffer leather of softer materials. The softer ones are better for filling volume and the leather are good where taking up volume is not needed. They also do a good range of heat mold liners simiilar to intution, but not as big and bulky. Cheak them out.
Zip fit is a bit of an old technology, i find it a bit hard and cold.
Intutions are good and comfy but dont last that long in my experience.
