Inspect the foot on the recliner. Some chairs have feet that screw into the base of the chair. If this is the case, unscrew the broken foot and get a replacement from a furniture supply store. Take the broken foot with you to the store to verify the replacement is the correct size. Screw the new one in and resume using the chair.
Tape the broken foot back together with masking tape. Remove it from the chair first if you can but otherwise turn the chair upside-down while you do the repair.
Drill two holes into the foot at a 90-degree angle to the break through the tape. Place a 4 penny nail into each hole. Cut the heads off the nails first with a diagonal cutter for a cleaner look. The nails reinforce the wood around the break to help prevent crumbling.
Remove the masking tape from the foot and apply wood glue to the break, pushing the two pieces together firmly. Wipe away excess glue with a cloth. Wrap the wood in wax paper and hold it in place with twine.
Remove the wax paper and twine the next morning and use the diagonal cutters to cut the nails down more if they protrude. File away any rough edges with a nail file.
Reattach the foot or turn the chair back over to resume use.
