wow.. all I can suggest is a vinyl tras. that might look weird tho.. mabey carpetman has a suggestion ..

I'm not a big fan of laminate flooring on steps but metal Schlüter might work for your stair treads. Schlüter is designed for ceramic tile but they do have it so that it is flexible.

Thanks for the ideas.

a couple of smaller companys have made curved transitions for laminate,find out who is the big flooring supply house in your area and call them.they are made of rubber or vinyl.

Can your step be cut to have a 45 degree angle? then possibly you could use transition strips.
