Discrete 1.4 Inch Lift

The CALTO IK302 inserts add 1.4 inches of height while remaining completely hidden inside high-top shoes or boots. Designed for unisex adult wear, they suit anyone who wants extra stature without changing their footwear style. The black finish stays invisible once the insole is placed inside the shoe.

E-TPU Popcorn Rebound Cushioning

E-TPU popcorn rebound technology absorbs shock with a lightweight 2.3 oz construction that adds minimal mass to each step. The material compresses and returns energy to reduce impact on joints during daily wear. Users should allow a few days for their feet to adjust to the incline and altered pressure distribution.

Trim-to-Fit Size 8-9 Compatibility

Each pair is supplied in a size 8-9 range that can be trimmed for a precise fit inside the chosen shoe. No additional accessories or software are included; the product is a standalone insert. The simple design means immediate use after optional trimming, with no setup required beyond the break-in period.

Questions about this item

How do I install the CALTO IK302 insoles in high-top boots and what step do people miss?

Remove the existing footbed, place the 1.4 inch lift flat against the sole, then wear for short periods first because the incline shifts pressure to the ball of the foot.

When will the E-TPU popcorn rebound layer need replacement?

The lightweight foam compresses gradually; replace the pair once the 3.5 cm lift feels noticeably lower or the shock absorption fades.

What limit appears first during all-day wear?

Reduced stability and increased forefoot pressure become apparent before the 2.3 oz weight is ever noticed.
