Of the many variations in the Cochise family, my fave is probably the Cochise 110. Mind you I haven’t tested it, per se, but my time in the Pro Light with a flex rating of 130 suggests the 110 would be more to my liking. If you like a stiff flexing boot the Cochise Pro 130 or Pro Light will probably be right up your ally, especially if you tip the scales in the 200+ pound (90 kg) range. Aside from the flex of the cuff, the Triax plastic lower shell insures there is no rotational loss of control with the Cochise, yet it is relatively easy to modify if you have a foot that demands a bit of punching or grinding.
Aside from personally preferring a softer flexing cuff there are a ton of features to like about the upper end Cochise boots. The sole blocks can be swapped between an alpine DIN toe and heel block, or Tech soles.
A strict count of the buckles suggests only three in combination with a velcro power strap. However, in the womens 100 flex version, and mens 110, 120 and Pro 130 version the power strap is enhanced with a buckle that yields a smooth but tight grip around your lower leg. A side benefit of the buckled strap is how easy it is to flip open to allow for more range of motion when the cuff is switched to walk mode.
The Pro 130 walks well with a solid 10° of rear cuff motion. Admittedly it can’t compete with the rear motion of a rando race boot, but it makes walking a dry trail noticeably more comfortable than many sidecountry boots that retain a bit of franken-stride, like Garmont’s Prophet.
The walk mode switch is a solid metal-to-metal latch which delivers a healthy 3-point contact between the cuff and lower shell. It is very rigid and will not yield beyond the prescribed angle – 16° – without serious force. Too much for me, maybe not for you. It would be nice if the forward lean angle could be easily increased, but Tecnica only provides one locking position, and moving it will require tools, time and skill.
My only serious complaint is with the Cochise Pro Light. It comes with a tongued, heat-moldable Palau brand liner that has some nice features (higher density foam in cuff and L-pads around the heel) but is rather thin. That isn’t my biggest gripe though; dropping the buckle on the power strap is. Tecnica’s excuse is they wanted to save 40 grams on the buckle to keep it a “lightweight” boot. Nonsense! Those 40 grams add way more power than weight and besides, if you really were trying to make a light weight boot that competes with rando light AT boots you’d need to shave a lot more than 40 grams not to mention the already nice walk feature would have to get better too. The good news is the holes for the buckle are already molded in to the cuff and with a $40 set of buckles and a bit of McGyvering you can convert the plain velcro power strap into a more powerful and functional buckled version.
As long as you recognize the Cochise won’t win any lightweight awards I’d say stick with the Pro 130, 120 or 110. Even though the liner for these models is heavier than the heat moldable Palau, it is more comfortable and improves a downhill performance more on par with a full alpine boot. Besides that, it comes with a nice rubberized sole for hanging around in a hut, something absent in the anemic Palau liner.
