I just took Puma [0]'s new running shoe, the Cell Voltra [1] ($100), out for a test run.

The first thing I noticed was that the shoe is incredibly light. Being the curious sort, I put it on my digital kitchen scale to weight it. One shoe clocks in at 10.75 ounces — an ounce lighter than my Under Armour [2] running sneaks.

The Cell Voltras capitalize on Puma's 10CELL technology used for building soles. Essentially, it's a layer system designed to create cushion and shock absorption as well as rebound. To see what I thought of these sneakers, just .

When I wore these shoes for strength-training workouts, to break them in a bit before wearing them on a run, I liked them. The front of the shoe felt thin, so I could really get a sense of the floor. The heel is nice and stiff, which seemed to provide support. But when I wore them running, I didn't feel like there was enough cushion on the ball of my feet since I strike mostly toward the front of my mid-foot. I felt like I was practically running barefoot. The insole was rather thin too, so my feet felt vulnerable. I think if you're a heel striker, this shoe might work for you, since the heel is stiff. I will definitely use this shoe for strength training and plyometrics, but not for running. Style-wise, I like how the shoe upper looks like a classic Puma — simple, with a flash of silver.

You can find these shoes at Finish Line [3].
