As a further development of the already successful X-Line range, Healthy Step were asked to manufacture a firmer version that could be heavily modified without affectiing its structural integrity.The X-Line 70 is so-called as it has a shore value of 70, compared to a shore value of 50 in the standard X-Line.
The X-Line 70 is a low profile device. Due to its high shore value this device can be adjusted by grinding and trimming to create intrinsic posting meaning less bulk in the shoe.




As the car approaches the bridge, it slows to go up the incline. Calcaneal plantarflexion is reduced when the heel meets the mid-foot saddle.

At a safe speed, the car crosses the hump of the bridge. The foot is stabilised when fully loaded on the saddle.
Once over the hump, the car accelerates away. The 1st ray drops into the recess and encourages the MTP joint to bend, the heel raises and sagittal movement within the foot has been maximised.


If you have been issued with a pair of these insoles and wish to purchase another please go to

 due to its very high density it may be worth considering the X Line RIF as an alternative.

We are happy to advise on all aspects of individual orthotic selection.
