I bought these a size bigger to use in day-long alpine climbs. They have worked great for me for that use. I can also walk with them on, something usual on apline routes where there are long ledges. Very comfortable.Never used them for sport climbing or bouldering..
I'm new to the rock climbing sport. (2 months).these shoes fit great and perfom great also. I couldn't believe the difference in my climbing after switching from the rentals. I know comparing to rentals isn't saying a whole lot but these shoes felt great. Great price for a great beginner shoe.
I got these shoes for my brother when he started climbing, and he likes them just fine. I chose these because they are really inexpensive for the brand, the rubber is stiff and sticky, and the shoe doesn't need much of a break in. I would say it is comprable to Evolv Defy in price and quality. The main difference is that the Defys have more sensitivity and is a bit more comfortable, but the Tarantulace has better edging and rubber. The shoe doesn't stretch too much, and the laces allow you to keep it tight, so I would say there is no need to downsize for this shoe.
I sized these shoes for comfort to learn trad (39, I wear a 38 in Katanas for performance). They're more comfortable than the Evolv Royales I started climbing in, but they're still not truly comfortable just because of the fairly cheap last (unless you've got really flat feet). Spend more on a better pair of shoes if you're already committed to rock climbing, even if you want comfort. I would have been better off with Mythos or just a larger pair of Katanas. They're still a great cheap way to start climbing.
I am a novice climber (2 months) and this is the first pair of rock shoes that i owned. but i have been very pleased with them so far. i have a pretty low volume heel, and this shoe is the most snug on my heel that i have tried out of nagos, evolv defy, and scarpa helix. it fits pretty comfortably. but it does stretch so be sure to buy them pretty tight. i wear size 10 street shoe and i bought 42.
