Cosmetic Blem:

Our Blems are built to the same high quality control standards with the same materials as our non blems. These are cosmetic issues only and do not affect the function of your board. We use blemish items for our personal demos and have no issues with function or durability.

Cosmetic blemished boards may have a steel rail that had a rough weld grind or slight bubble in the powdercoat from the hanging process. Some have a weld bend that is beyond our normal tolerance and the straight edge has a slight bowing. This is due to the spring back from the thick steel we use.

The board top may have a repaired top or bottom layer split or an artwork imperfection.

When you purchase this item we will contact you to discuss the board top options available. Thanks!

Surf Inspired:

The Surf Original takes dry land training to a new level. We shaved weight off the nose to carve a turn with quicker precision compared to our elliptical models. The stable fish/swallow tail keeps your base grounded as you whip this board in, out and around. Bump up your dry land training and your next session will be amazing.

Dominate Every Wave:

Surfing indoors just got easier. Plenty of space for two balls or half balls for upper body exercises and full body coordination. Practice pop up moves, cross stepping and getting deep into the tunnel. This board easily allows a variety of positions and will continually challenge your sense of balance.

Balance On These:

The Surf Original features a steel rail system that allows you to create 16 different types of boards. A perfect balance board for learning skill progression. Create your own unique combo that suits your needs. Add Balls and Half Balls for your training. Features a steel rail system you can attach Resistance Bands to expand your exercise routine.

5" Small Balls: These Balls are fast and keep the board moving for beginner riders. They will keep the balance board close to the ground for easy stopping. Use two for a double pivot board and have a lot of forward and backward motion for skill progression and quick foot work. Use one ball for a multi-direction board for a high level of movement.

5" Medium Balls: These Balls are a better size for riding on one ball compared to the 5" Ball. The height is good for carving turns and to transfer weight from foot to foot. Using two balls under the board gives you lots of side to side tilt when in a deep stance.

5" Large Ball: The Large Ball is for advanced riders who have great control and coordination. Being 8.5" off the ground gives you huge turns without grounding the board. The weight also carries your momentum and requires greater muscular strength to control this fast moving board. Expand your set up with this ball as you progress.

8.5" Half Balls:
This size Half Ball is the best and will give you enough tilt and ability to rotate. Use one for a wobble board tilting in all directions. Use two and create a rocker board for basic movement. Half balls allow you to progress from the basics of balance or multi-task in complex motions as you progress. Use a 5" Small Ball and 8.5" Half Ball for the Thrasher and Rock and Roll combos to simulate rough water conditions. Use a 6.5" Medium Ball and 8.5" Half Ball for the Big Drop combo to simulate unpredictable training with quick saves.

Resistance Bands: Increase your postural control and spine stability with Resistance Bands. Simply loop the straps around the board and attach the bands and handles. Adding the upper body control increases your muscle activation, focus and overall training effect.

Elysia's Notes:

I love the Surf Original with the 8.5" Large Ball and so do advanced riders. There is something about being high off the ground and letting the weight of the ball carry your momentum until you are hanging on by a toe. Pop-ups and deep stance training is great on the 6.5" Medium Balls. The larger board size compared to the Freestyle Original gives me a little more room for board grabs and wide stances.

Balance Board Progression From Beginner To Advanced:

Basic Combos:
  1. Rocker Board: 2 Half Balls
  2. Wobble Board: 1 Half Ball
  3. Single Pivot Board: 1 Half Ball and 1 Ball
  4. Double Pivot Board: 2 Balls
  5. Multi-Direction Board: 1 Ball
Specialty Combos:
  1. Rock and Roll: 5" Small Ball rolling inside a 8.5" Half Ball at each end
  2. Thrasher: 5" Small Ball rolling inside a 8.5" Half Ball
  3. Big Drop: 6.5" Medium Ball fixed tight inside a 8.5" Half Ball
Add the Resistance Bands to any combo for 16 different systems

5 of 5 Love my new board February 12, 2020
Reviewer: Phoena Walker  
I absolutely love my new SI board set up.  Elysia helped find me exactly what I was looking for and the most affordable way to get it.  The customer service was fast,  personal,  and perfect.  Everything arrived quickly and in great condition.  I've been riding every day and cannot speak highly enough about the quality of the product and the experience purchasing it.  I let all my friends play on it and encourage them to up their game by getting one.  It is an investment, for sure,  but there's nothing else like it on the market,  and this is built to last.  Plus,  it came all the exercises you could ever imagine.  LOVE IT AND THANK YOU!

5 of 5 a new balance experience April 10, 2018
Reviewer: john espo  
an unreal balance board that i have yet to master, but i'am getting there. The board with the single 6.5 ball leaves no stone unturned in the realm of balance. Bosu, gyro, indo boards don;t come close.
