While I do prefer to be freepaw when I'm in the house and doing other tasks within close proximity to my house (e.g. putting trash out to the curb and obtaining the day's mail), most of the time when I go out it's not exactly feasible.
On the rare occasions that I do go out, it's usually to play Pump Pro (for which I need to wear my Reeboks for maximum performance), and to get to the bowling alley I play it at I have to walk along a busy road (with lots of garbage, ditches, jagged rocks, and other nasties alongside it). So I usually end up wearing my tennis shoes when I go out (though I do switch it up on occasion when I'm not playing Pump by wearing my flip-flops, which I sometimes even take off while I'm out).
