< 50
TOO SOFT & NOT DURABLE
Mats with a shore rating below 50 are too soft for combat and stand-up training. Their low shore rating and softness means that the jigsaw teeth are more likely to tear and break, making them a poor choice if you want a long-lasting and durable option.
50 - 55
SAFE & DURABLE
All SMAI mats have a shore rating between 50 - 55 degrees this means that they are perfectly balanced between safety and durability, as all things should be. Mats in this range are more durable than softer mats (below 50) and are safer than the harder mat (above 55).
> 55
TOO HARD & UNSAFE
A shore rating of 55 and above are too hard for safe combat training. Their hardness reduces impact absorption and increases the likelihood of injury
