Rewards Program Terms and Conditions
Last updated January 1st, 2020
Opting-in to Moosejaw Rewards:
All users must accept these terms and conditions and create an account with Moosejaw to opt-in to the program and earn, accrue, retain and redeem Moosejaw Reward Dollars (MJ$). The program is FREE to join and membership is ongoing until or unless the user requests to be removed or is removed due to abuse of the program. Users can opt-in to the program while checking out on Moosejaw.com or at one of our stores or at any time within 30 days of purchase to accrue the MJ$ earned on that purchase. Once opted-in to the program, MJ$ will earn and accrue for redemption as described below until the MJ$ expire or the user leaves the program.
All information collected and used to facilitate the Moosejaw Rewards program is directly related to the program's ability to provide value to the customer. A customer opting-in to the Moosejaw Rewards program is a separate action from establishing a user profile as a result of making a purchase.
The program opt-in requirement was added on August 6th, 2019. Existing program members prior to that date must still formally opt-in and accept the terms and conditions to continue to retain, earn and redeem MJ$. Pre-existing program members that fail to opt-in prior to June 28, 2020 will be removed from the program, and any unused MJ$ will be voided. We really, really don't want to that to happen, so please opt-in or we'll feel terrible.
Leaving Moosejaw Rewards Program:
You may choose to leave the Moosejaw Rewards program at any time by logging in and clicking on the “Opt out Rewards Program” link within the My Account Summary page, Email, calling 877-MOOSEJAW (877-666-7352) or in-store with help from our employees. If you leave the rewards program, any unused MJ$ will be voided upon completion of your request.
Earning MJ$:
All items we sell are eligible with the exception of gift cards or other items specifically noted. Full-priced items earn 10% back while discounted items earn 2.5%. "Discounted items" includes items on sale or discounted via coupon code or use of MJ$. You do not earn MJ$ for shipping or tax charges, only from the item value. MJ$ expire two years after earning and are redeemed on a first-in, first out basis (in other words, we always use your oldest MJ$ that are closest to expiration).
Checking & Redeeming MJ$:
On Moosejaw.com, just sign-in on any page to see your available balance. Once signed in, you will see your available MJ$ and maximum that can be redeemed in the payment section of the checkout process. In stores, provide the email address attached to your account to learn your balance and apply to your purchase. We will also send you a monthly email that details your balance and other account activity. This is a transactional email that you will receive even if you are not subscribed to our marketing emails.
Bonus Rewards Promotions:
Every so often, we'll have special offers where you can earn bonus MJ$, like an additional 10%, 20% or 40% back. So if we are running a 50% back special offer, and you buy a regular-priced item for $100.00, you will receive MJ$10.00 in base points, and a bonus of MJ$40. These special offers may have a cap on how many bonus MJ$ you earn during the promotion, but you will always earn the base Reward Dollars. Make sure to check us out on our social channels for other ways to win some extra MJ$!
MJ$ on Gift Cards:
You don't get earn MJ$ when you buy a gift card, but you do get MJ$ when you spend a gift card. Sorry gift givers. You're welcome gift receivers.
Product Returns and MJ$:
If you return an item, we deduct the MJ$ earned on that item from your balance. If you used the MJ$ and your balance is less than deduction, then your refund is reduced by the difference.
Program Abuse:
The intent of the program is to provide our loyal customers with a way to buy great gear for less. Moosejaw reserves the right to remove any user from the program and zero out their MJ$ balance if Moosejaw determines that the user is abusing the program by buying for resale, attempting to game the program or any other reason at Moosejaw's sole discretion.
Are you Sure?
Our Rewards Program is completely FREE and easy to use.
By opting out, you forfeit all the Moosejaw Rewards Dollars your currently have in your account, which is basically throwing away free money. What would your grandmother say about that? If you're 100% sure, please click "OptOut" below.
Earn 10% back on all full-priced purchases on Moosejaw.com or at our shops (2.5% for discounted items).
The program is FREE. Just register and join during the checkout process. So Easy.
After joining the program, you'll receive your MJ$ as soon as your order ships. Then the next time you shop at Moosejaw, you can redeem those MJ$ to get awesome gear for way less.

Special order items take longer to ship
We want to make extra-sure you realize that you've added a special order item to your cart. These items take a little longer to get to you because we have to order from the manufacturer first. The "Est. Ship Date" is the date we expect items to leave our warehouse... so add your chosen shipping speed to see when it will show up at your door.

Best Running/Scrambling ShoesBest running/scrambling shoes on the market. I use these for scrambling the flatirons in Boulder, CO and it's the one shoe that does it all, especially on slabby rock. Out of the box, the rubber is not as sticky for scrambling, but wear them in after a few runs/hikes and the rubber only gets better and sticker as it wears. It is no surprise that over 50% of the other serious scramblers I see out there are wearing the same shoe.

Good shoeDidn’t blow me away but it’s a solid shoe. Wish it had more room in the toe area. Because of this I will look somewhere else my next shoes. Vibram megagrip is stickier than the Frixion stuff on these shoes, but it’s good enough for class 3 scrambling. Some side protection near the toes would be nice, because I can already see nicks of the mesh material after using them on scree and talus.

Big lugs, comfortable rideI bought these after trying out the La Sportiva Karacal, which was a very comfortable trail shoe except for the elastic band mid-foot that caused a massive blister. I have not experienced any blistering in the Mutant, but it did take three pairs to find the right size. In a Nike running shoe I wear a size 11 US, in the Karacal I wore an 11.5 US, in the Mutant I wear a 12 US. The Mutant seems to run small even by La Sportiva standards.
In terms of feel, the shoe tightens down quite a bit mid foot with a complicated lacing system. It will definitely take some adjustment to find the right level of tightness. The security of the lacing system along with the large lugs leads to confidence when descending. I mostly run on rocky trails in the Colorado front range and these shoes are just about perfect for that environment. The longest I’ve run in these so far is a 7 mile outing and the cushioning was great. The shoes do seem to be a bit bulky, but I’ll take the extra protection on the rocky trails that I run. If you run on mostly dirt, gravel, or well maintained trails these shoes might be a bit overkill and you could opt for a lighter shoe.
Removed a star because of the lacing system which seems overly complicated to me and difficult to adjust.

Too smallLove La sportiva. Wear the ultra raptors and akasha. Tried same size in mutant but it is way too small. Couldn't size up Moosejaw didn't have any other sizes. Had to return.

Finally found my favorite trail/mountain shoeHave tried so many shoes (and spent way too much money) on finding a great trail and mountain running shoe. Trying to find something to work with my foot (narrow heel, normal to slightly wide forefoot), something that has great cushioning but isn't so soft that the midsole collapses on fast, technical switch backs, and mountain trails, and something that has great grip, especially on wet rock. Enter the la sportiva mutant. This shoe fits me so well, and if you have a similar foot shape to me, and run on technical trails, would highly suggest trying it out. Have done runs up to half marathon distance, but have absolutely no hot spots or blisters so far. Can't wait to take it on longer runs. Only con would be the weight, which is on the higher side of trail shoes but runs much better than the stated weight. Would check it out and hope la sportiva keeps it in production! Also as with all my la sportiva trail shoes, would recommend going up half a size form your normal size.

StableA 6-1 210 and with flat feet this shoe is the best all around trail running shoe I have found. The 10mm drop is ideal for hilly terrain and reduces stress on the achilles. A little tricky to put on/off but that's no deal breaker at all

LA SPORTIVA FIT NOTES La Sportiva shoes are built on European half sizes which are smaller increments than US half sizes. This gives us four extra sizes per size run, which gives you a better fit! MORE SIZE = BETTER FIT!
