The insole is considered as the soul of the shoe. In this case, since we are talking about gym and flat shoes, the ideal material is Biagioli felt.
Universal size adult insole that can be cut to fit sizes 24 to 45, absorbent and anti-odor felt insole.

The buttress is the rear reinforcement of the shoe that serves to give stability in the heel area and to make the shoe more robust. It is the element that protects the heel and, for this reason, is more rigid than the rest of the upper. The buttresses we supply are not shaped, therefore suitable for being placed during the joining phases, and are made of first quality heat-activated morel fabric. One size to be trimmed.

What you will receive when you order this item:
-20 universal size cuttable insoles
-20 buttresses One size fits all to be trimmed
