Looking for input on these with first hand experience. I love Croc Echos so much but im looking at these for something more open and breathable for the beach. They don't look like an easy on and off shoe compared to echo and croc classics. I just want to know how secure they feel, is the strap elastic, how the soles feel if they were used on gravel, asphalt or on long walks on sidewalks. If I am a 9M, should I size up, down or stay true to size.
