This is my first experience with a Pear Izumi shoe…I guess when I think of the brand, I think biking or triathlons–neither of which apply to me.  When the opportunity arose to try out a pair of Pear Izumi’s isoTransition shoes, I wasn’t about to pass it up.  Pulling them out of the box, they felt SUPER lightweight and my initial thought was that this shoe was not going to do anything for me…they’re not even pink.  When I tried them on, they felt loose but once i adjusted the way cool bungee cord laces, they felt snug and fit like a glove.   I had heard they run small, so I sized up 1/2 a size but I’m wondering if I should’ve stuck with my normal sizing…when wearing socks they feel great but I know, as a tri shoe, they’re to be worn without, and they’d definitely slip if I wasn’t wearing a slightly padded sock. The lacing makes for a really easy slip on & off–another advantage for the swim/run transition.   This is a flat shoe and while I’m making more of a switch to minimal running, I’m not quite ready to jump in feet first.  I didn’t wear this shoe on any run longer than 10 miles and after the 10, my heels were a little tender (what a good excuse for a pedicure).   I’d like to get to the point where I can do a long run in them because they’re such a comfortable, lightweight trainer.  I have put 50+ miles on these shoes and that was the only issue I had with them.  Other than a day of sore feet, they are very comfortable.  I like the minimal feel with that little bit of cushion.  Another really neat feature of this shoe is the self-draining midsole.  This would be a crucial addition if I could actually swim…seriously, it’s an ingenious detail.  I had a little trouble with the “holes” because I ran a few times after a big rain and rather than drain the water, it was let in.   Just say no to soggy socks!   Someday I’ll do a tri and when I do, this would definitely be a shoe I’d consider racing in.  Hopefully by then they have some better colors to choose from…
