Yes , I recommend this product
The Hayatsukis are awesome shoes! These are incredibly precise fitting snug and tight around the heel. The lacing system lets you loosen the pressure on your toes while keeping the heel and ankle area nice and tight. They're plenty warm for temperatures between -10 and -15 Celsius while you're moving. However, as soon as you stop and stand still, you'll start to feel the cold. I personally found them comfortable for belaying around -7 Celsius. I typically have issues with heel lift, but these boots grip my ankle like they're a part of my body. I've never had heel lift issues or toe compaction with these boots, and when I finally wear them out I'll buy this identical pair again.
