Can I trade in an iPhone 6 for an iPhone 5S?

I have had an iPhone 6 with Verizon for about 5 or 6 months and I'm kind of over it. The size really bugs me and it is really slippery. Will I be able to walk into Verizon and trade in my iPhone 6 for an iPhone 5S? I'm still locked into a two year contract.

No, too late to return it, so you are stuck paying for the phone, until it is fully paid for, if you are making installments payments.

Now if you paid in full for the phone when you got it, all you need to do is sell the phone, and use that money pay for a new iPhone 5S a decent case and AppleCare Plus.

You have to pay to break the contract. Best way is to go to verizon store and complain about the phone.
