Heat Moldable vs Dual Density vs Ultra Soft Orthotics

Choosing the right orthotic insole depends on whether your feet need firm structural support, custom modification, or extra impact cushioning.

In this guide, we break down the main differences between single density heat moldable blanks, dual density options, and ultra soft orthotic insoles.

Heat Moldable Blanks vs Dual Density Orthotics

Single density heat moldable blanks are CNC-milled from EVA foam, maintaining consistent firmness from the heel through to the forefoot. They can be placed directly into footwear as an off-the-shelf support or customised by adding wedging in a clinical setting. Dual density heat moldable orthotics build on this design by adding a thicker, softer top cover layer. This provides additional comfort for active wearers while preserving a surface that glues and grinds easily during custom adjustments.

Where Ultra Soft Orthotics Fit In

Unlike CNC-milled heat moldable blanks, ultra soft orthotics are injection-molded from polyurethane and feature integrated Poron cushioning pads under the heel and ball of the foot. They share a similar supportive arch contour as heat moldable options but focus heavily on impact absorption. This makes ultra soft insoles a great choice for general daily fatigue, arch discomfort, or forefoot pressure where rigid customization is not required.

Key Features of Each Insole Style

  • Single Density Blanks: CNC-milled EVA providing consistent firmness from arch to forefoot.
  • Dual Density Blanks: Combines firm arch support with a softer top layer for active use.
  • Ultra Soft Insoles: Polyurethane build with extra Poron cushioning for impact absorption.
  • Customisation Ready: Heat moldable blanks permit easy grinding and addition of custom wedges.
Podiatrist TipIf you require precise structural correction, heat moldable blanks allow for tailored clinical modification. For general arch strain and hard-surface cushioning, an ultra soft orthotic offers immediate comfort.
