Five Ten Guide Tennie Review (2026): Stealth C4 Approach Classic

Why you should trust this review

I bought the Five Ten Guide Tennie with my own money and put it through real approaches and scrambles. Five Ten did not provide it, and I have no relationship with the brand. The Guide Tennie is a long-running, trad-climber favorite, so I came to it to find out whether the legendary grip still holds up against newer approach shoes and whether the well-known durability and quality concerns are deal breakers.

Real use on rock, in cracks, and on the trail miles between is what reveals an approach shoe’s character, and that is what informs everything below. I will be honest and specific about both the strengths and the weaknesses, because the Guide Tennie is a tool with a clear purpose and clear limits, and buying it for the wrong use, like long trail days, is exactly how people end up disappointed.

How we evaluated

I used the Guide Tennie for the job it is built for: approaching and scrambling on rock, with easy climbing zones and crack work mixed in. I tested the grip on hard, smooth rock where sticky rubber matters most, jammed the slim profile into cracks to judge the fit, and used the precise lacing to dial in the climbing-zone fit on technical terrain. I also walked the trail miles that come before and after the rock to assess comfort over distance.

I paid attention to how fast the Stealth C4 rubber wore on abrasive rock, how the canvas-and-suede upper held up to chimney and crack scraping, and the consistency of fit and finish. The conclusions reflect real approach and scramble use, not a single outing.

Grip on rock

The Stealth C4 outsole is the reason this shoe exists and its single biggest strength. On hard, smooth rock it is the stickiest rubber I have used in an approach shoe, gripping confidently on slabs and smears where lesser rubber slides. That grip is what lets you commit to easy climbing moves and exposed scrambles in an approach shoe rather than swapping into climbing shoes, and it is genuinely class-leading.

The toe rand carries the same Stealth C4 into a climbing zone at the front of the shoe, so you can edge and smear on small features with precision. Combined with the precise lacing that extends toward the toe, the Guide Tennie lets you dial in a snug, performance fit for the technical sections. For approaches that involve real rock contact, the grip and climbing-zone design are exactly what you want.

Fit, crack performance, and lacing

The slim, climbing-precise last is a deliberate choice that pays off on rock. The narrow profile slots into cracks far better than chunkier approach shoes, so when an approach involves crack scrambling or jamming, the Guide Tennie fits where a fatter shoe would not. That slimness is part of what makes it a trad-climber’s shoe rather than a hiking shoe with sticky rubber bolted on.

The extended lacing reaches toward the vamp, letting you tighten the fit precisely over the whole foot for technical terrain. I could snug it down for climbing zones and the security that brings on small holds. The fit is performance-oriented and dialed, which is exactly right for its purpose, though it means the shoe runs slim and you should account for that when sizing.

Upper durability

The canvas-and-suede upper is well suited to the abuse approach shoes take. It held up to chimney and crack scrapes that would shred a flimsier upper, and the suede reinforcement at the high-wear areas resisted the abrasion of jamming the foot into rock. For a shoe that spends time grinding against stone, the upper’s durability is a real strength and means the shoe takes punishment without falling apart.

This is a long-running model with a proven design and a genuine following among trad climbers, and the upper construction is part of why it has endured. The trade-off, as I cover below, is in the rubber rather than the upper, so the part of the shoe that contacts the rock wears faster than the part that scrapes against it.

The honest limits

Three real downsides temper the praise. First, the Stealth C4 rubber that makes the shoe so grippy also wears noticeably faster than a harder compound like Vibram MegaGrip. Soft, sticky rubber is a trade: you get the grip, but you pay for it in outsole life, so expect to resole or replace sooner than a shoe built for longevity. Second, the stiff midsole, while good for edging, is uncomfortable for long trail miles. Beyond about five miles of approach hiking it becomes tiring, so this is a shoe for short, technical approaches, not all-day treks.

Third, quality control has been inconsistent under Adidas ownership, with reports of variable fit and finish, and limited stock cycles can make finding your size harder. None of these undermines the shoe’s core purpose, but together they mean you should buy it knowing exactly what it is for: grippy, precise short approaches and scrambles, not long-distance comfort or maximum durability.

Who should buy the Five Ten Guide Tennie?

Buy it if you want best-in-class grip on hard rock for short, technical approaches and easy climbing, and you value a slim profile that fits cracks and precise lacing for a dialed climbing-zone fit. It is the right pick for trad climbers and scramblers who prioritize rock performance and a durable, abrasion-resistant upper over trail comfort and outsole longevity.

Skip it if you need a comfortable shoe for long trail approaches over five miles, since the stiff midsole gets tiring, or if you want maximum outsole durability, because the soft Stealth C4 wears faster than harder rubbers. Skip it too if inconsistent quality control or hard-to-find sizing would frustrate you.

The verdict

The Five Ten Guide Tennie remains the approach shoe I trust most on hard rock. Its Stealth C4 rubber delivers class-leading grip, the slim last fits cracks where chunkier shoes cannot, the precise lacing dials in a performance fit, and the canvas-and-suede upper takes real abuse. The honest limits are equally clear: the sticky rubber wears fast, the stiff midsole is uncomfortable on long trail miles, and recent quality control has been inconsistent. Buy it for short, technical approaches and scrambles where grip and precision matter most, and it excels. Buy it expecting long-distance comfort or maximum durability, and it will disappoint. Matched to its purpose, it is a recommendation.
