Best For....

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 semi-gusseted tongue and FitLock secure the shoe to your foot.  This shoe has a snug fit and some athletes choose to go up 1/2 size for a bit more room. 

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.

Spark review

These are my third pair. Super comfy for my “challenging” feet. Unfortunately they start to fall apart within 6 months.

Love the way the souls don’t stay packed with mud

Awesome shoes

The thing that I like best about my Sparks is that as an older runner who sometimes runs in the dark these shoes make me feel safer. I’ve done a few trail runs in them but they are my go to shoes on the pavement if there is any dampness.

Spartan running shoes

Excellent shoes soupier gripping for down hill running but you must start making you shoes in wide I hate I had to get a size to big for me 13 wide is perfect and hard down you will have the best shoes on the planet

Great shoes!

I’m a solid Age Group OCR racer. I picked these up at a Savage race after realizing I’d left my running shoes in my car an hr away. They were great right out of the box! The Sparks are super light weight, good room in the toe box, and have fantastic grip. They feel like part of your body, not clunky rubber strapped to your feet. Like a firm sock with protection and grip on the bottom. Very very cool shoes! I have two pairs of Solomon Speedcross 4, I love the grip, cushion, and spring but felt I was always on the verge of rolling my ankle because I can’t connect with the ground. The Sparks make to feel very grounded. The only things I found that take some getting used to are: 1. At first the tongue felt too tight and like it was digging into the front part of my ankle, to solve that issues I switched the laces to the other holes and loosened them. You can still keep the rest of your laces tight even with the loosening of the top hole. 2. Being a lower drop shoes, they don’t automatically encourage forward momentum, you have to work for it more. 3. Occasionally I’ll feel some rocks through the sole, hasn’t made my feet tender so far, but idk how it would be on very rocky terrain, I’m going to take the rock plate from Ultra’s and use that for super rocky training runs. I’ve only used them on softer trails so far. But I believe in these Sparks enough to take ‘em to Utah for the NS Beast. Will ABSOLUTELY BUY THESE AGAIN! These are fantastic shoes! PS. I usually wear 4.5 size kids shoes (Keen, Nike, etc) bought 5.5 Sparks that fit perfectly. Go up in size 👍
