Exit row seats should meet your needs.

Check on seatguru before booking any flights.

Exit row seats are now premium seats that have a surcharge.

And far cheaper (last I saw was $50 for an overnight transatlantic flight) than an upgrade to the premium economy/business/first class seats (double fare or more).

Still only half of my femur fits on that economy seat. On 17-20 hour flight it's still major pain.
