Cork: This is the most common cork in the orthopedic market. It is firm enough that it will hold up for heavier patients, yet light enough that it will not break down.
EVA: This material is ideal for patients that need medium support and moldable orthotics.
Black Zote: Ultra light-weight material but extremely firm support. Ideal for the patient that needs moldability and firm support.
XPE: Medium to firm support. This is a lightweight material that is designed to provide firm but soft support.
White Zote: This is a very soft and lightweight material. Perfect for the patient that needs soft and moldable orthotic support.
BirkOcork: This is the firmest arch fill. This is the original Birkenstock cork. This cork is known to last for years. Birkenstock cork works for heavy patients or patients that can tolerate rigid support.
EFM: Extra firm material. We use a 1/8″ 80 durometer EVA between the top cover and arch fill. This adds more support to the orthotic.
THK: This plastic material inserted between the top cover and arch fill used to provide rigid multi-density device.
