Step Steel ST-Goal 3mm Runner features precision that will make the difference. From the very start of production, STEP monitors the raw materials used to product the runner to make sure everything meets their standards. With stability comes increased confidence. The cut qualify of the runner profiles is preferred amongst Goaltenders, since the equipment used in production is able to produce identical profiles for a perfectly symmetrical pair of skates. Maintaining your profile over time shouldn't be that difficult --- to keep your runner profile in good condition for as long as possible, STEP has created device guidelines to help perfectly center your runner during sharpening that results in a profile that increases your stability in the crease.
