What muscles are being missed?
Hamstrings, adductors, and maybe calves. To fix this
- add stiff legged deadlifts, swiss ball leg curls - not a lot but needed for balanced development.
- alternate normal squats with some split squats or single-leg box squats which will challenge the lateral muscles - and, as a result, make your legs look more like tree-trunks
- if you're a marathon type, do speed work, sprints, bounding...improves the calves and muscle tone incredibly

swiss ball leg curls = useless, am I missing something squats not working hamstrings-I think not, put it this way start with single leg squats and once you can do these at a rate of one per second with full range of motion and with balance then think about squats with weights, for 99% of distance runners the SLS using bodyweight or weight vest(no more than 15% of BW) is sufficient, try step ups and lunges in all three plans of motion, med ball throws as well
