Shoes to recommend daily trainers

1) Asics Novablast 3 - good cushioning, good enough to do tempo & faster runs.
2) Nike Pegasus 39 - daily trainer from Nike, suitable for long easy runs, can be use for faster runs too, I've personally used them and have clock around 750km in these shoes

Most important thing is to make sure you enjoy what you're doing and maintain consistency. Your VO2Max will improve over time.
