I had been developing foot pain. It lasted all day and would not go away. Podiatrist ordered custom orthotics for me. I broke them in and acclimated myself properly and the foot pain still did not go away. I ran into an add for Vibrams and decided to give them a try. Since then my feet have been pain free. I LOVE my Vibrams, and wear them as my regular shoes.
The Jaya LR are a lightweight Vibram that has more coverage in the front and heel than the classics. The grips on the sole are nice, but the shoes can still be slippery on the waxed gym floor. They size like the classics, as long as you understand that the leather will need a while to stretch so the uppers and toes may initially feel very stiff and a little small.
Overall, they nice shoes for daily wear, light cross-training. The shoes are very lightweight and flexible and fit nicely. My last pair made it through 6+ months of daily wear.
They don't get 5 stars because I prefer the Jaya base model which is the most comfortable shoe (feels like a slipper) I have ever worn.
