I'm with DJ on this one, the quality of these boots look a little on the crappy side.
You should go to a bike shop and try some boots on, get a pair that is comfortable for YOU. If youre looking to save $$$ get the make and model of the boots and hit the net and search for an outlet that will sell them cheaper. There are heaps of online stores that have great prices.

Remember if you buy poor quality boots and you come off and the boots don't do their job & protect your feet it could make walking later a bit difficult.
I like the look of the boots the DJ has pointed out they look like they offer more protection.
Without actually seeing the boots myself, the boots you have looked at on ebay don't look as though they have the quality of protection of the ones DJ has looked at. But at least they are better than runners (trainers, sand shoes ? what do you guys call them?)
Remember to always wear good protective gear, you may never intent to crash but its the silly chick in her car talking on her cell putting lip stick on that will make you thank yourself for wearing good gear.
Safe riding, here's to never 'using' the protection that they offer

. If you understand where I'm coming from!!!!
Now, of my high horse. [8D]
Enjoy
