This is a compact blue and black walking aid with adjustable straps. I purchased this product because I broke my right ankle and was using crutches, which caused pain in my hands and armpits. Walking has become remarkably easier. The fact that I can use both hands is also very helpful. - Brand: iwalkfree 3.0 - Color: Blue and Black - Type: Walking Aid - Features: Adjustable Straps - Design: Compact and Lightweight Includes box and user guide.
