Keds, Sperry, Sebago, Clarks for your deck shoe and boot needs.
As for dressier shoes, try something Rockport or Steve Madden for sub-$100 jawnz. It's pretty hard to fuck up a classic shoe like a brogue/oxford if the materials are decent. There's little to no branding on formal shoes, so it just comes down to quality/feel.
Dress shoes aren't worn as often as casual shoes and are maintained with polish/protective agents, so it's easy to find nice second-hand leather shoes. Older shoes were often made with more care and better materials, and most can be resoled if need be. If they get too beat for formal events, they migrate nicely into casual wear. A pair of semi-beat wingtips in red/orange leather with an absorbent insole are nice in the summer time.
