A Story of One Camino and My Keen Jasper Zionics

"Hi Keen Team! I don’t usually leave long reviews, but this story literally changed my life. It all started a few years ago when I dreamed of walking the Portuguese Camino de Santiago. However, there was one thing holding me back: footwear. I didn’t own any professional trekking shoes, and I didn't want to buy boots just for one trip since I don’t wear that style in my everyday life. In February 2026, I bought in Poland a pair of Keen Jasper Zionic (the yellow ones). During a long walk with my family that same day, I kept repeating: "Oh my god, these are so comfortable! The most comfortable shoes ever. " Right then and there, it clicked — these were the shoes I could finally walk my Camino in. I booked my one-way ticket that very same evening. I’m back home now, and after covering 300 km, here’s what I can say: Design: Simply brilliant. They look fantastic. Comfort: It was a pure joy to walk in them. Yes, they got a bit heavy in the rain, and yes, I got a few blisters—but when you’re pushing 50+ km a day, that’s to be expected regardless of the shoes. Durability: They look a bit "seasoned" now, and the fabric near the heel has worn down slightly, but considering the 40+ km daily load, they performed incredibly well. The best part? Every time I met fellow pilgrims on the trail, I told them the story of how buying these shoes was the final push that sent me on this journey. It made everyone laugh and smile. :) I decided to write to you because this story is deeply rooted in my journey. I know this review is very personal, but I felt the need to share it with the people who made the shoes that took me there. I’m attaching a few photos of my Jasper Zionics in their 'natural habitat' on the roads of Portugal and Spain. I also bought 2 more pairs. Keen LOVE, Roman"

Annapurna base camp trek

"I took this shoes on the Annapurna base camp trek 3 weeks ago. They super performed. Not a single blister, no hot spots, super comfortable. No sore feet. We did a super aggressive trek. 3 days up, two days down. It was my 65 bday! Doing Epic stuff!!!"

These shoes are great and

"These shoes are great and my favourite. However I had the same ones before and they split. So the build quality could be better. That aside the shoes are very comfy and practical. Great for walking. The soles could be stronger also...to last longer. Despite that I think they are great and I like the company. So many shoes are just made of plastic / rubber nowadays...that seems to fail...any ideas on making this better...and in-line making the shoes last longer...!?"

Very comfortable now they’re broken

"Very comfortable now they’re broken in. A lot more water resistant than I expected. I’ve been for 2 hour walks in wet fields and still held up, which is great. Look good, easy every day shoe for big walks"

— Terry H. (5/5)

These shoes look great but

"These shoes look great but an awkward fit, especially after wearing them in. Size guide recommenced a half size up so I bought my usual and the size up just in case. Stuck with my usual size but wondering if I should have actually sized down. There is very little flex in the shoes, especially over the top of the feet, which is probably why issues only present after wearing them in. Toe box is a good width, great for my wider than average feet but it’s also very high which means there’s excessive volume above the toes. This just means pulling laces tighter which causes the tongue to uncomfortably fold in on itself over the toes. Length seems fine but there is heel slip even with a runners loop (and again, I have wider than avg feet). Not overly comfortable for walking in either - very rigid. Would advise anyone to buy size above and below and really try on before you commit. Bought for every day shoe, not for hiking."

The perfect shoe! I bought

"The perfect shoe! I bought for my partner and he hasn’t taken them off since, he said they’re his favourite shoes and has commented on how insanely comfortable they are. Now I need to get myself a pair!"

"Love the looks, true to size, and comfortable!"

Great Shoe, But Didn’t Last

"I bought these to use as an all around shoe; they seemed stylish but rugged, suitable for hiking. I would say that’s mostly true, and they are very comfortable with a midsole that’s better suited for walking and standing for longer periods of time than the classic Jasper. The outsole has just enough grip for hiking without being too aggressive. However just a few months into owning them, the rubber at the toes is peeling up on both shoes. I’m pretty disappointed in the quality of this shoe. Especially since I’ve owned a pair of classic Jaspers for two years that look no worse for wear (aside from dirt on the suede). So, I still think these shoes are dope, but maybe stick to streetwear uses and don’t work them too hard."
