  • Sizing Inconsistant

    I am normally a size 7.5 and have a pair of regular Jasper shoes that are size 8 and just fit. Having this experience, I ordered a size 8 when the Keen Customer service representative indicated that Jasper Rocks were running true to size. When they arrived and I put them on my feet they were too tight so I returned them and ordered an 8.5. The 8.5 was even tighter on my foot then the size 8. I've given up on ordering Keen's by mail and will only purchase them from a brick and mortar store in the future.

    Cute, but hard and narrow in toe

    Like most newer Keen designs, these have a narrow (rather than wide) toe box. I ordered up, and they fit, and are cute--but are just not *comfortable*. The shoe is surprisingly hard in the toe and while some Keens feel supportive and comfortable, wearing these feel punishing. These also have very little arch support. Usually that works for me (I have a low arch), but found my feet were aching from lack of support. I expect a lot of my Keens compared to other brands, because support, width and comfort are what I rely on to keep me going. These are going back.

    Good Shoe

    This is a great looking shoe and put together very well. I did fit me about 1/2 size too small so potential order 1/2 size larger.

    Not what I was hoping for.

    I really like the look of the Jasper Rocks SP and they seem to be very well made, however the fit was not what I expect from KEEN. I wore them around the house for a few days and found the toe box to be extremely constricting and uncomfortable and found it necessary to return the shoes. I own several pairs of KEEN shoes because they are very comfortable and fit so well. That was not the case with the Jasper Rocks SP. I will continue to buy KEEN shoes and would recommend them to anyone – just be careful about the sizing and fit.

    These run small in length compared to other Keens

    Ordered these is same size as my other 6 pairs of Keens and they were toe-jamming short in length so had to return. Now out of stock.

    I had to return this shoe. It was too narrow.

    returned. It was too narrow. Couldn't even get the shoe on my foot. I've been wearing Keen shoes for 10 plus years and I've had to return about 3 pairs over a several year period due to being too narrow.

    Good looking, comfortable shoe

    These shoes are so comfortable. I wear them all of the time. The grey color goes well with everything. I like the lacing system, how you can just pull up on the laces to tighten the shoes. This shoe does run small. I always wear a 12. Ordered a 12, & my ties were at the very end of the shoe. Returned, & ordered a 13, & the fit is perfect.
