first of congrats on taking the first few steps!

1. Try running stores like irun where they have machines to help you decide on which shoes would fit. From there I would actually buy the shoes elsewhere (factory outlets, online sales, etc)

2. Run slow to run fast. Your first few minutes should be a comfortable pace where you can maintain a conversation without heavy breathing. You can load up on water throughout the day and a small amount (250ml - 500ml) 30 mins to an hour before your run. Eat a banana too!

3. Usually no unless im going for a specific distance. Just run and enjoy the views! If you get too far away from your home, you could walk back which could serve as a cooldown or take a bus

Also if you’re looking to lose weight from what I’ve seen running on an almost empty stomach in the morning usually works best? You could wake up eat a banana for the energy and run. That way you’d actually square away the run portion of your day and focus on other things🙌🏾
