CHAUSSURES
"Idéales pour la promenade ou la détente."
— Jean-Louis D. (5/5)
Amazing shoes again
"I have a pair of Mammuts a few years ago that I have tried to wear out, even migrating them to yard work and cutting wood. They won't wear out. These new ones look even better-built. I'm excited to start the whole process again."
— BRET W. (5/5)
these are very comfortable shoes.
"these are very comfortable shoes. They are extremely grippy and perfect for hiking and possibly some light running"
— Derrick S. (5/5)
Super!
"So comfortable and a great fit!"
— Daniel D. (5/5)
Clutch travel shoe
"While I wouldn't want to wear these shoes on a 4th class scramble, they're surprisingly comfortable with decent grip. The convenience of being able to wear them as slips means I don't have to bring flip flops to the crag. Where these shoes really excel is as a travel shoe. They pack down very slim and the styling works well enough with casual wear."
— Steven S. (5/5)
Wonderful approach shoe
"These shoes provide a comfortable fit with good traction for any approach. The sandal or “belay” mode as I like to call it is easy to get into and lets your feet relax and breathe after a climb. A must have for any crag day!"
— Gabe O. (5/5)
Good purchase
"Men’s US size 10. , true to size. Well made, durable, comfortable shoe. Will definitely consider buying more of this brand."
— Toby F. (5/5)
Difficult fit
"I find the shoes run small and narrow. I think it's due to its elastic heel support, which pushes my entire foot slightly forward. I went +0. 5 than my usual size, but it still gives me the same problem. I don't know if +1. 0 could have helped. . .
I feel like it's in between sandals and shoes and not steady enough for a long walk or hiking."
— Yusuke T. (2/5)
Alnasca Hybrid Exceeds Expectations
"This shoe is lightweight, easy to put on & take off without unlacing, fits securely, & has a sleek unique look. The affordable price was a welcome surprise!"
