I like the Justin ropers. I prefer the leather soles. Rubber soles scare me. I am afraid that I can't get loose from the stirrups with them. I wear a pair of Justin lace-up ropers very similar to those in the picture you posted except that they are bullhide and very old. (They have been resoled several times.)
When I did my sudden unscheduled dismount on Friday, I had no problem at all with getting stuck in them. Happily, they turned me loose and allowed me to try my new helmet on the dirt, unhampered. :)
Seriously, if I had gotten stuck in the saddle, I would not be typing now.
