The Solution
Our collaborative journey began with a thorough discussion of the target application, ensuring alignment with 5.11’s exact needs. Like most runners, the PT-R Inure needed to strike just the right balance of lightweight cushioning, ergonomic shape, and energy return — all with a durable foam material that would last the full life of the shoe.
To achieve this, we combined two tried-and-true INSITE technologies: the INSITE ArchRelief™ insole shape with INSITE EcoComfort® Energy poured PU foam.
INSITE ArchRelief insoles use a low-profile arch support shape to provide targeted underfoot pressure relief. This shape is especially ideal for athletic footwear, adding ergonomic comfort without adding bulk or constricting the foot against the upper.
For the material, we turned to INSITE poured PU solutions, which can be engineered for a broad range of exceptional cushioning and performance benefits. The PT-R Inure uses INSITE EcoComfort Energy foam, made from 25% bio-based compounds, optimized for powerful rebound and springy underfoot cushioning for active underfoot applications — with a more resilient compression set for supreme durability.
Thanks to a methodical and adaptive approach, our two teams were able to find the exact right high-performance insole shape and foam for 5.11’s new high-performance shoe design.
