We are visiting Petra and Wadi Rum in May. I want to know if my tennis shoes (Keds) would be Ok or should I buy lightweight mesh type running shoes like Skeches GoRun or a lightweight mesh Nike product? I want my feet to be comfortable, not hot and sweaty. I don't own a pair of Skeches/Nike type runners yet so I have no experience with how my feet will feel in them. I am considering buying a pair as I am unsure if the tennis shoes will have enough cushioning from the desert heat. I am in my late 60's on a tour with others to Petra and the Wadi Rum on the same day so I expect there won't be that much time to climb or explore different areas in Petra. So tennis shoes or a leightweight mesh type runner like Skecher.Nike? Thanks for your reply.
