Incomparably comfortable, miraculously hugging the foot so safe and comfortable even going up and down stairs as they kind of gently cradle the foot and move with it unlike the moulded plastic lookalikes which slip and slide hazardously and are downright dangerous for some people. Although not marketed as a specialist shoe for people with complex mobility/balance/foot and ankle'spine, fatigue/arthritis/fybromyalgia issues I can as a long term sufferer of all these issues highly recommend them as the best, most comfortable, lightweight, supportive, helpful footwear of all the types out there. But above all perhaps for me, the safest. I have had a triple ankle fusion and throughout the pre surgery, post operatively with a huge orthotic boot and now with no orthotic these have become my go to footwear in and out of the house as they hug my basically knackered feet and ankles with supportive and gentle lightweight care. I have huge balance issues and can't alter my gait to incorporate small changes in floor level but these help hugely and the customer support is superlative. The shoes are also super value for money and last for years even with heavy diuty daily use. I am a super fussy editorial journalist and I never write reviews unless I believe in a product. These rock. But them. Accept no alternative.
