- Brand: FLUX - Model: TX-BOA - Size: 27.0cm Selling because I'm buying different boots. Purchased new last year and used about 10 times. The insole was replaced with a different one from the second use, so the original insole was only used once. After each use, I washed the boots with water on the outside and removed the inner lining to dry them. There are scratches on the right boot from the strap, but they are still usable. Size: 27 - 27.5cm
