I just looked those up on their site. Those are pleather boots that you can get on ebay or the like for about $40.00 typically. It's good to know that they're pretty durable and worth the money as they can be a great alternative for those on a budget.
I ordered the officially licensed Obi-Wan Ep. III boots from MRL a few months ago to see what they were like. They got returned almost immediately for a refund.
For Star Wars boots, my personal recommendation is to go with JDOS Productions. He can make any design boot you want to your measurements. While they are more expensive, they are worth every penny because of the quality and fit of his work. Considering that these are custom made pieces, his prices are really really reasonable. The only downside is that you might have to wait a while. But quality takes time.
I also own a pair of Han Solo boots from Todd's Costumes. These will work well for many different SW costumes. Luke ANH Ceremony, Luke ROTJ Jedi, X-Wing pilots, Rebel Troopers, etc. Great boots! Great quality, affordable, and durable.
