So iLL Main Street Review

If you have your heart set on buying a pair of these shoes we suggest sizing them the same as your street shoes. For example, our tester wears a size 10.5 street shoe and he was happiest with the same size for his So iLL Main Street.

Performance Comparison

The So iLL Main Streets seem most at home in the gym or sport climbing.

Edging

Our testers concluded that the edging performance was subpar. The Main Street comes equipped with 3 mm of So iLL's proprietary Dark Matter rubber. This stuff seemed sticky enough, but the soft sole on the forefoot provides meager support for serious edging. These shoes also seem to be more voluminous than most, which left our slim-footed testers with excess space for their feet to slide around in.

Edging in the Main Streets felt clunkier than their soft sole or thin rubber would suggest.

Cracks

Crack climbing is not an intended use for the Main Street, and their performance reflects this. The toe box dimensions are large both horizontally and vertically, making it difficult to get them inside thin cracks. There is also rubber coating the toe upper that adds extra material and makes them even less suitable for narrow constrictions. Finally, the mild downturn of the entire shoe positions your toes with a slight curl that causes sustained jamming to be painful.

Thin cracks are difficult to climb with the Main Street because the high-volume toe box make it challenging to get any rubber inside.

Comfort

The mild downturn and wide dimensions of the Main Street boost its comfort compared to more aggressive or narrower shoes. Some of its other features, however, harm its score. Our biggest complaint is the soft sole, which supplies limited support and accelerates foot fatigue.

There is lots of flex in the soft sole of the Main Street. The apex of this flex, however, is located behind the mid-foot where human feet don't usually bend.

Some testers also aren't fans of how high the synthetic upper extends at the heel because it irritates their Achilles tendons. Those who were brave enough to crack climb with these kicks experienced sharps pressure points while foot jamming from the plastic buckles on the velcro straps.

We were disappointed with the loose heel on the Main Streets because it made heel hooks feel less secure.

Pockets

The considerable volume of the toe box is a real disadvantage for crack climbing, and it does the same for pocket climbing. The toe box design is one of the most bulbous we've seen in both horizontal and vertical directions. This makes it harder to fit these shoes into small pockets. On steep terrain, our testers also lamented the loose fit of the heel cup. The excess space reduced sensitivity and made marginal heel hooks even more challenging.

With 3 mm of Dark Matter rubber, we expected the Main Streets to feel sensitive. An imprecise fit, however, left us once again disappointed.

Sensitivity

The Main Streets are fitted with 3 mm of Dark Matter — a thickness that is roughly a half-millimeter less than average for shoes in this review. We, therefore, anticipated a sensitive feel, but we were once again disappointed. Despite the thin rubber and soft sole, our testers found it hard to feel small footholds. The voluminous upper also creates an insecure fit that further reduced our confidence when trying to utilize tiny features.

The velcro closure boosts convenience at the crag or the boulders, but the plastic buckle creates a pressure point during crack jamming.

Value

Compared to a top-shelf premium climbing shoe, the Main Street presents some modest savings. Although the lower price might be tempting, we believe there are other models that offer better performance at the same price point. For this reason, we don't consider these shoes to be an exceptional value.

The rubber coating the upper adds welcomed grip for toe hooking. However, its considerable thickness was a hindrance when climbing thin cracks.
