Not sure about the specific differences in glucose utilization between the soleus and the gasctroc (the other main calf muscle) but in general, yes. Calf raises should have a similar effect. The key factor seems to be the soleus doesn't fatigue as quickly, allowing this to be sustained to a point where the muscle energy source shifts to a more long term type of fuel. As for people who bounce their calves? Absolutely - this is called NEAT (Non Exercise Activity Thermogenesis) in scientific research. Its lumped in with general movement - walking, climbing stairs, etc. This can account for a few hundred calories per day. Here's an overview study that claims up to 350 calories per day: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6058072/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6058072/
