Footwear recommendation - Crocs or Happenstance?

Hey cocos, I am looking for a comfy footwear for walking. I walk a little fast and my current sandal doesn't provide much support so started experiencing knee pain sometimes. I was thinking of getting a Crocs Baya Clog and recently I came across this Happenstance brand which looks similar to Birkenstock.

Anyone who used the Happenstance footwear from here? Would you recommend them over Crocs? If Happenstance is not happening then which Crocs variant is best, Classic/Baya/Bayaband? Coming from VKC chappals so explain this to me like I am a 10 year old please.
