Pros
  • The Wool Runner is an absolute 10/10 for comfort and casual wear. Everything else they've made is always a little bit of a trade-off from that.
  • They offered incredible comfort, especially for someone like me who struggles with plantar fasciitis.
  • I've worn the new Wool Runners NZs for 3 months and they're the best shoes yet. I wear them everywhere.
  • I was shocked when I got them, expecting them to be garbage. The sole has less forefoot cushioning but they feel like similar shoes to the NZs.
  • Cloud-soft comfort with dual-density Featherbed™ insole
  • Sleek minimalist design
  • Sustainable materials (merino wool, TENCEL™ fiber, SweetFoam® sole)
  • Machine-washable
  • Refined fit and improved support vs. previous versions
Cons
  • This is why I will NEVER buy shoes that use naked foam cushioning as a sole. You really can't complain about short lifespan.
