Charlton wrote a review of Black Diamond Custom Telemark Ski Boot - Men's on February 4, 2009
These boots provide great control. I ski the G3 Reverend with Hammerhead bindings. Last year I had Garmont Syner-Gs; I could control the ski, but I had to do more foot steering than I like and thought it was almost more ski than the boot could handle. The Custom drives the ski really easily. The boot has excellent lateral stiffness, and transfers power to the ski beautifully. I was a little concerned that it would be too stiff for me (I'm 5'10", 155lb), but once on the snow, I found the flex to be smooth and easy. This boot is a huge performance upgrade from the Syner-G. The Boa lacing system is easy to use and provides a snug and comfortable fit. The walk mode does a good job relaxing the cuff of the boot, and the ski mode provides aggressive forward lean. I have not yet toured in them, but they are very comfortable at the resort. If you are an aggressive skier looking for a powerful boot, you will be very happy with the Custom.
