welcome to So iLL...
We started shaping holds in a Southern Illinois barn over two decades ago. The space has changed since then—now we’re in St. Louis, all 10 of us under one roof—but the heart of this place hasn’t. We’re still family-owned, self-financed, and hands-on with everything: design, photography, marketing, operations, logistics, packing…all happening just a few feet from each other.
Your support is what keeps this work moving. Thank you for for being part of what we're building.

Nearly every aspect of our shoe manufacturing process is intricate, small batch, and by hand.

Years of trial and error have led to hand shaped lasts that ensure premium performance and fit.
Love the bag. It fits everything. It’s pretty tough and holding up in Seattle weather. Really comfy. It feels deep but allows for width if needed. The inside pocket would fit a laptop and has an outside zip to fit chargers etc. this bag will fit a ton.
My second hoody. My gf kept stealing mine because it’s so comfortable I bought her one.
These are the most comfortable and versatile shoes that I’ve ever had. The quality is on point as well. Thank you so much Jason and the So Ill crew for all you do! I will definitely be telling my friends and family about them.
I got the black one for myself. Love it!😊
Bought it as a gift. He’s gonna love it!
Conceptually, putting this hold on a keychain is hilarious. Very well made and perfect companion for any set of keys
Really love this shoe. The color is great, shoe itself is soft. Would definitely buy again and recommend it to others.
Purchased for my teenage grandson. Matches shoes and ski cap i previously purchased. He was extremely happy
Always fantastic products from the So Ill team! My kiddos will absolutely love the 2 charms we got them for gifts!
Very satisfied with what I got. Great variety of holds and families, even got a super size pipe hold! Will definitely buy another box when it’s available.
Love the bag and there was something in it for all of the family! Great Buy!! I would suggest it to anyone that is a So iLL Fan!! Very generous gift bag!!
I'm signed up for text alerts and received notification about this release ahead of time and had to purchase it immediately! It shipped later that same day and arrived about a day later and was more than worth the price: roll-top backpack, four shirts (including one limited release), two pairs of socks, and the lavender beanie I have been eyeing for a while. I am more than ready for my next roam!
The wife said I looked too good to go out without her! lol
super tacky, helps a lot
I dry fire off of *everything* and my skin is so, so dry. Super psyched to have this chalk! Especially looking forward to using it in Maple in summer, when the humidity gets down below 9%, I can't hold any of the cobbles, and stopping mid route to spray spit on my hands isn't really an option (til I fall off). This chalk will make climbing so much better on those days!
