I want to sell nike blazer shoes on ebay, but i need the postage cost. and what would be the best packaging?

The USPS offers Priority boxes that fit shoes for free. I would take the shoes to the Post Office and ask them which is less expensive: to mail Priority or to mail Parcel Post. Just pick a zip code far away from you. I live in GA, so I pick 90210 for CA.

I would offer both shipping options to the buyer. In some areas, Parcel Post is more expensive than Priority. If you use PayPal to create your shipping label, the tracking number is free. Add in the cost of the box, if you have to buy one to send it Parcel Post, it may be less expensive to send it Priority.

Go to the Post Office and weigh the box with the shoes and any packing material. Use that weight when you create your listing. If the box weighs 2 lbs 3 oz, move it up to 3 lbs. Sometimes the listing ends and the shipping isn't calculated correctly. You cannot ask the buyer to pay the difference. The difference is less than $1, so consider that your expense in gas to drive it to the Post Office.

You is not the problem, it is nike blazer shoes
