Columbia Columbia Sanguil Omni-Tech YM3607 Hiking boots featuring a durable design and comfortable fit. - Brand: Columbia - Model Name: YM3607 - Colors: Red, Blue, Brown - Condition: Used Size: 26.5cm Thank you for viewing. This is a Fall/Winter 2013 model, but looking at it now, it has a very luxurious construction typical of Columbia. I used these about once a month throughout the year, so there is some wear and tear, but I think they can still be used.
