The Martombike Iron Man PRO insole is most often chosen for the half and full Iron Man distance. The construction is thin enough not to interfere with the running stage, and before that it guarantees comfort on the bike despite its small size.
It is a several-layer construction of dense foam made with thermomolding technology. Additional perforation enhances its breathability. Its other advantage is flexibility - the insole works in every direction. Due to the technology of manufacture and the thickness of the foam, this product should be counted among the fast-drying ones - an extremely important feature that athletes appreciate in the stages following the swim.
The insert is also perfect for spinning!
