The GEL-Cardio Zip was originally designed for the pre-diabetic/diabetic consumer and has revolutionised the Health Walking category. It has, however, also become widely worn by non-diabetics looking for a smart, comfortable and roomy shoe that is well suited for either work or leisure activities. The upper utilises a zip construction on the medial side in conjunction with a traditional lacing system for great fit and ideal entry and exit from the shoe. Medial placement of the zip has two major advantages. Firstly, to maintain a traditional lacing system which improves the overall image of the shoe, and secondly, placing a zip on the medial side makes the zip much more accessible for someone who is overweight/ obese or has mobility issues. Comfort is enhanced via the use of super soft garment leather, a bamboo lining and an internal heel protector.
