CATERPILLAR Colorado Boots For Men  (Yellow , 10 UK/India)

I want to buy these boots in Delhi. But it says "Not available with any sellers." I tried with pincodes of Delhi, Mumbai, Bangalore, Hyderabad, Kolkata and Chennai. But the same warning. I am guessing this boot is not at all available. Maybe just a trick to lure customers to buying something else and stay on the site/app.
