I wanted to get some custom magic items for my character. They are described below.
1) boots of speed, striding, and springing
-basically, the abilities from boots of speed and boots of springing and striding combined into one pair of boots. What I want is the abilities from boots of speed combined with the longstrider spell for the +10 ft movement.
boots of speed = 12,000 gp
boots of springing and striding = 5,500 gp
So, 12,000 + 2(5,500)gp = 23,000 gp
or with just the longstrider 1st level spell
12,000 + (1)(1)(2,000)(1.5) = 15,000 gp
