Toddler shoe question - so lost!!

My daughter has been walking for 2.5 months now and her first pair of shoes were a pair of See Kai Run Stevie First Walkers. Well, she has outgrown these and needs a new pair but I’m a little lost. When would a toddler no longer be considered a new walker and when can they put out in a harder soles shoe?

I was thinking of getting her a few pairs of cat & jack shows but I’m not sure if those would be too hard?

I never stressed about this until I followed Miletsonesandmothedhood on IG😂
