I have zero experience in running for fitness. I used to be in good shape simply from having a more active lifestyle and doing regular manual labor, but since moving to a different country, I've adopted a more sedentary lifestyle as a result of being jobless and lacking a social circle coupled with depression problems (and uh, being an avid gamer).
I would like to get started with the Couch to 5k running program. However, I do not own a pair of running shoes. I've read conflicting things about getting started as a runner. Some say that while you're just in the beginning of the program, it's okay to just use your regular everyday shoes until you decide you want to upgrade as the program intensifies. Others say you definitely need running shoes if you want to do any kind of running.
I'm not sure what the best advice is. I have no experience I can draw on to make a sound judgement of what I should do. Can I safely use my regular, daily use shoes for starting out doing low-intensity daily exercise or should I try to purchase proper running shoes first?
Edit: My current shoes are a pair of Men's Energy-3 Punisher shoes I purchased last December in the US (though I'm female, I usually purchase men's shoes for regular wear. I don't know if this makes a difference in running shoes). I've mostly used them for daily use and regular speed walking.
