The wearer of these magical boots has a base movement rate of 12", regardless of size or weight. This speed can be maintained tirelessly for up to 12 hours per day, but thereafter the boots no longer function for 12 hours — assume they "recharge" for that period. 

In addition to the striding factor, these boots also have a springing factor. 

While "normal" paces for the individual wearing this type of footgear are 3-ft long, the boots also enable forward jumps of up to 30-ft, backward leaps of 9-ft, and vertical springs of 15-ft. 

If circumstances permit the use of such movement in combat, the wearer can effectively strike and spring away when he or she has the initiative during a melee round.

However, such activity has a degree of danger, and there is a base 20% chance that the wearer of the boots will stumble and be stunned on the following round; adjust the 20% chance downwards by 3% for each point of Dexterity above 12 of the wearer, i.e. 17% at 13 Dexterity, 14% at 14, 11% at 15, 8% at 16, 5% at 17, and but 2% at 18 Dexterity. 

In any event, the wearer increases armor class value by +1 due to the quickness of movement these boots imbue, so armor class 2 becomes 1, armor class 1 becomes 0, etc.
