A bonus to a creature's speed (like from the boots of striding and springing) grants the creature a bonus to its Jump skill checks: each +10 ft. over 30 ft. grants the creature a +4 bonus on Jump skill checks.
Likewise, a reduced speed penalizes a creature's Jump skill checks: each −10 ft. below 30 ft. causing the creature to suffer a −6 penalty on Jump skill checks. (This is one of the reasons the typical lightfoot halfling's +2 racial bonus on Jump skill checks is viewed with disdain, the "bonus" merely decreasing its Jump skill check penalty from −6 to −4 because of the lightfoot halfling's reduced speed.)
