Right,
Thomas Lang - I'm watching his
DVD "Creative Coordination (and Advanced Foot Exercises" right now... awesome stuff! I can fire away 16th on the double pedal, but playing crazy broken patterns is a different story! His DVD covers a huge array of what you can do with your feet. Numerous patterns, multi pedal orchestration... This DVD (3-DVD set) has a running time of 7 hours (incl. bonus material)!
Also bought
Virgil Donati's "Double Bass Drum Freedom" (book & CD) - cool but really challenging stuff. E.g. mixing up singles with doubles on the bass drum, and playing through countless syncopated patterns and/or odd signatures. Just wanted to mention - another tutorial which should drive you crazy.
As a superb starting point I'd recommend Derek Roddy's endurance exercises (start slow enough and it won't feel like endurance, speed it up - oh yeah):
Derek Roddy's Drum Lessons & Solos Part 2

Continue watching the other parts to get the idea. Those exercises are not only great for your feet but also for your hands, to tie hands & feet and get them in sync. He's demonstrating those exercises @ 180 bpm. If this is too fast - slow down as needed, the concept remains the same. Derek is doing singles mostly, sometimes doubles, too (not in the above video). Highly effective to balance out your limbs and get in sync. I got into drumming 16 months ago and I'm quite happy to have taken up exercises like that almost from the start.
For more exercises, weaker foot workout, blast stuff, multi pedal orchestration check out Derek's DVD
"Blast Beats Evolved" (I've bought it recently) - superb stuff also.
George Kollias also has a great DVD out there,
"Intense Metal Drumming". Plenty of ideas for footwork, handwork, patterns... He does swiveling but no doubles.
One of the most radical DVDs on foot technique I know is
Tim Waterson's DVD "Techniques, Motions and Applications for Bass Drum Playing".
http://www.twothreeonetwomusic.com/
I know no other tutorial covering so many (basically ALL) foot techniques. You'll find EVERYTHING and more you'll ever need - heel-up, heel-down, singles, doubles, singles/doubles w/ swivel or glide, groups of 3 notes, interlaced doubles... just crazy stuff. Tim is up to around 360 bpm!!
Don't forget that throne height, posture, pedal distance etc is quite important for double bass. Just days ago I bought
Matt Ritter's DVD "Unburying the Beater" which is a great round-up to the techniques I've been exploring. This DVD explains how to avoid annoying extra notes and has helped me within days! Highly recommended. It's not "flashy" but addresses precisely the technical aspects of executing the motions correctly. It also includes proper throne height and drum setup for most comfortable playing and thus, best results. This DVD is great to enhance your awareness, optimize the motions and clean up your bass drum playing.
The total of the above mentioned DVDs will help and provide stuff to work on for a lifetime. If you're serious...
You can find lots of tutorials or DVD snippets on YouTube though.
If you have
"Stick Control" you could apply everything in there onto your feet - basically (with practice!!) they can do what the hands can - in terms of speed, timing, patterns. Many drummers just don't dare to go this route... "Stick Control" contains endless patterns you could use for your feet. Some of them might be easy to learn, but most will be a total workout. Mixing up singles and doubles takes a lot of practice. You'll need patience! (I need it also.)
