The VJ Spark:  

VJ Spark is a lightweight, fast attack shoe.  With a combination of an EVA midsole and legendary VJ grip featuring butyl rubber, the Spark will help you fly like never before.  The all-new, breathable mesh nylon upper is designed for comfort and breathability.    The wider toe box gives your foot plenty of room for the long haul, while the semi-gusseted tongue and FitLock secure the shoe to your foot.  

Use the Spark for short, fast work - either on training days, or for racing.  You will feel a solid connection to the terrain you are on, bringing confidence in your step and speed to your stride.  Or, use the Spark for longer, hillier runs where grip and the lower weight will give you an advantage.

Four and a half stars

I found the Spark to be really light and comfortable. The grip was good on dirt, sand and rocks. Arch support was good. The forefront of the sole could use more support. Adding my additional green insoles helped blunt the foot strike impact. My longest run so far in the Spark has been only 6 miles. It’ll be interesting to see how they do on longer distances. The shoes fit me true to size even with the extra insole, I wear my running shoes snug.

Predictably wonderful.

These shoes are light, comfortable, and supportive - and of course have amazing traction. These shoes are predictable and confident with every step. Love them!

The Spark is a fun "weapon" to have in your arsenal for shorter trail and speed sessions. The grip and snug feel make them my go to for all my Hill Repeat training sessions!!!

Solid Mid Distance Shoe

Another excellent shoe by VJ. Light weight, solid grip as always, and made me feel confident on trail. Highly recommend.

Sticky, but small

Love love love the grip on these shoes, I feel super secure (and fast!) on sketchy surfaces. Unfortunately, the forefoot is too cramped for my hobbit feet to cram into them for more than a few miles at a time.
