"A do it all perfomance shoe that provides all day comfort"
This is my first season on the masais and after 30 years of climbing behind me I have pretty much heard all the hype of a "do it all shoe that performs well in all aspects". So, needless to say, I approached these shoes with much of the same skepticism that I have other shoes in the past. That being said, I have to say that my first impression of the Masai is an extremely positive and think that just maybe this is the shoe that lives up to the "hype"First of all it is a narrow last, it fits much more snug in the toe box and mid foot than the Ra (Tenaya's Velcro answer to the 5.10 Anasazi VCS). the heel cup is less pronounced than its Velcro counterpart making for less useless space and a comfortable fit while still pressing the foot forward directing the weight over the front toe. It is stiff torsionally giving you great support on edges and narrow toe box allows you to stuff those toes into medium to small seams, cracks and pockets. Great on slabs and good sensitivity overall!
I have had the Tenaya Masai's for about 5 months, usually climbing 1-3 days a week, and I really enjoyed them...for about 3 months. The last two months the rubber has become increasingly less sticky and the shoe has lost a lot of its stiffness. My biggest gripe about the shoe, however, is how sweaty it is! I normally have somewhat sweaty feet to begin with, but this shoe is almost unbearable. The synthetic upper does not breathe at all. This compromises a lot of edging power as the shoe just rolls around my foot on dime edges (despite the excellent low volume last) Also they don't dry out either. I put them on 24+ hours after climbing in them and they were still fairly damp. An overall good vertical shoe, just not for us sweaty people.
