DeFeet Woolie Boolie 2 Merino socks



Excellent socks for winter riding. Extremely comfortable and fairly priced, but make sure your shoes are roomy enough.

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

We reviewed some Woolie Boolie socks on last year, but as winter comes around again it's time to test DeFeet's newer version with the ingenious name of Woolie Boolie 2 and longer (4in) cuffs. These socks are warm, comfortable, and fairly priced, but they're thicker than most cycling socks so make sure you've got shoes big enough to take them.

As the name implies, Woolie Boolie socks are made predominantly of wool, merino wool to be exact, which has excellent heat-retaining qualities. Merino wool is also very comfortable against the skin and not at all itchy.

Even better, merino keeps you warm even when it gets wet. And it also breaths and wicks moisture away from the skin, a feature only fully appreciated by those already wearing these socks and (according to DeFeet's the advertising blurb) sheep.

Without doubt, these Woolie Boolie socks will keep your feet warm in winter, but they're definitely thicker than 'normal' cycling socks, so you may find them a bit of a jam in your shoes (unless, like many wise cyclists, your winter shoes are a tad bigger than your summer shoes).

Even allowing for room inside the shoes, one downside I noticed on these socks was the large seam on the inside that sits across the top of the toes. This seam had 'lumps' at each end where there thread had been cut and secured, and these lumps were noticeable – and slightly irritating - inside the shoe when cycling. It's not the end of the world, and some careful positioning of the seam can move the lumps to a position where you can't feel them. They also seem to get softer after a few washes.

Although DeFeet have some spectacularly colourful socks in their range, the colour choice for the Woolie Boolie 2 is limited to dark grey, presumably on the basis they'll be under long tights and over-shoes most of the time.

These Woolie Boolie 2 socks retail at around £13, although you can find them for nearer 12 quid at your local bike shop and even less the usual on-line stores. Compared to other merino wool socks from other manufacturers, this is a good price. They are also available in an even longer (6in) version at a slightly higher cost.

I ordered these from two cycling shops, both sent me version 1 not version 2! Anyhow, they are the only cold weather socks I have and they are pretty good.

Recently I got caught out trying to get back to base before the rain started. I was wearing Gore trousers and the water was being directed to my shoes. The water was pouring out of the ventilation hole in the front of my shoes but my feet were warm. I think it was 6 degrees or less outside.

I use mine a lot, no seam issues here. Extremely comfortable and also work well in temps up to around 20 degrees as they wick so well. I plan on buying many more!

A quick tip for socks with lumpty seams, is to wear them inside out.

I know of a couple of "round the world" cyclists who swear by "Icebreaker" merino socks. No toe seams, extremely long lasting, and made from the finest New Zealand merino (better than ordinary merino, apparently).

I think if rather pay a bob more and get a sock with flat lock seams to avoid those bobbly bits.

I've got the old version of these and can't say i've ever really noticed the seam, even when wedged in the shoe with an under-sock, although I have had them a while - YMMV. I'm getting some more for cycling and non-cycling wear this winter, they're that good, plus you get a sheep on each sole ! Surely worth half the price on its own.

Perhaps the best bit of cycling kit I've got. I've had mine for a couple of years now, worn for cycling, in work boots, kicking about the house, the lot. No wear, no bobbling, no holes. Just warm, toasty, comfortable feet. Worth every penny.

My Woolie Boolies are about to start their 3rd winter and still look brand new, just like the review says they perform and are great quality.

Can you even '+1' a review?

Anyway, I've merino socks from Rapha, Endura and DeFeet, the Woolie Boolies are the most effective if not quite as comfortable as the ones from Rapha, of course that might just be the marketing telling me that  3
