First, Crocs are darn comfortable in any style and very supportive.  These canvas Melbourne slip-on aren't any different.  They are a light weight design and may seem cheaply made due to this.  They're not. However after several weeks of wear, they look like they may last till next season.
When I found out how comfortable Crocs were, I set out to find a pair to match my life style.  These shoes fit the bill.  I am active, walk a good deal, and needed cool an  all around/ knock-around shoe that has great foot support.
If you have a large or wide foot (13"+/-), then you might have a problem.  I wear a size 13+ and I'm at  Croc's limits.
Although they're ugly, I plan to buy another pair of these amazing shoes.  Once you put them  You won't want to take them off.
