Gear Review- Black Diamond Fuel Approach Shoes

Black Diamond Fuel Approach Shoes Review

Black Diamond has released their most advanced approach shoes yet this past Spring, the Black Diamond Fuel Approach Shoes. I’ve been testing a pair for the last few weeks and am ready to share my take on their comfort and performance. First lets look at the manufacturer claims and specifications.

Manufacturer Description

Engineered for days when the word “approach” actually involves full-on climbing, the Fuel is our most technical performance shoe. The Fuel’s upper combines breathable EnduroKnit, a durable stretch woven lateral panel, and welded TPU film overlays for maximum durability and precision fit. The internally overlapping tongue allows for fewer seams and a sleek comfortable fit with minimal bulk, while the lace-to-toe construction features webbing and scalloped eyelets for variable, adjustable fit and tensioning to suit different conditions. A climbing-specific forefoot construction allows for exceptional edge control and our BlackLabel Mountain rubber is ultra-sticky for superior grip on rock. Finally, a tag-loop on the heel and tongue gives you the option to clip the Fuels to your harness once you rope up.

My opinions…

Out of the box the first thing I noticed was the lightweight feel. My US Size 9 pair weighs 1 pound 5 ounces (600 grams) which is slightly lighter than the manufacturer claimed weight an about an ounce heavier than my LaSportiva TX 2’s. A fair comparison in terms of weight and support would be closer made to the LaSportiva TX Guide approach shoes.

The second most notable feature was the welded “TPU film overlays” especially on the upper around the heel. I’ve seen this technology used in high end waterproof jackets and using it on an approach shoe not only gives the shoe a very high tech look but also inspires confidence in the long term durability of the shoe.

Fit/Comfort

I went with a US Men’s size 9, EUR 42, and the fit was pretty spot on for my medium width regular arch foot. I probably could have sized down a half size but with a full length lacing system I was able to snug these up sufficiently for low 5th class climbing. I did notice some heel lift while wearing them around the house on Day one of testing but interestingly when hiking around Rumney NH I didn’t notice the heel lift. The heel cup could definitely be a little deeper. The wrap style tongue and padding was quite comfortable while testing with and without socks… something to consider in hot weather these actually felt pretty comfortable without socks. The EVA midsole provided plenty of under foot support and had noticeably more cushioning in the heel than other approach shoes in this category.

Performance

In class 2, 3, and 4 terrain these perform well as approach shoes. They definitely had adequate grip and comfort over 4-5 mile trips in New Hampshire’s rugged White Mountains. To test them in fifth class terrain I climbed a half dozen routes at Rumney, NH ranging from 5.3 to 5.7. They felt more secure while edging vs. smearing which I think may be in part to the rubber used in the outsole. The “BlackLabel Mountain rubber” feels a little stiffer than the compounds used in competing brands which makes these feel like the soles will have longevity with a small reduction in the coefficient of friction. As I’ve found with most approach shoes I’ve tested the friction can improve as the soles break in a bit. I usually have maximum confidence in my smear-ability once the “dots” on the soles have been worn down and the bottom of the approach shoe looks more like the bottom of a climbing shoe. Perhaps after a full season of use I’ll feel these smear a bit better.

Durability

It’s not easy to speak to much on durability when my testing window is only a few weeks long. That said a close look at the construction of these inspires confidence you will not wear through a pair of these in a couple seasons. They would certainly outlast some similar models with the futuristic welded seams and significant toe rand.

Summary

The Black Diamond Fuel Approach Shoes are a welcome addition to the growing list of approach shoes. The price and features puts them up against shoes like the LaSportiva TX Guide approach shoes and they certainly can compete. A slightly deeper heel cup would be nice and a softening and smoothing of the outsole over time will likely increase the security while heading up slabby terrain. I also think it is great that Black Diamond is producing a women’s version since options for women’s approach shoes haven’t always been there. If you are in need of some new approach shoes this is a model to consider, especially if you’ve worn Black Diamond climbing shoes before and know their sizing fits your feet!
