While Santa is busy delivering presents and eating cookies for one day a year, Mrs Claus is back up in the North Pole running around after the elves for the other 364 days. And now we know how she does it... Grab a pair of women's Nike Free 5.0 running shoes for $155 from Trade Solutions.

Specifications:

• The phylite midsole of the Nike Free 5.0 features a waffle outsole construction for a lightweight cushioning along with traction and durability
• The mid-sole also provides enough durability to double as an outsole, dramatically reducing the weight
• There are deep, gender specific carves (sipes) molded along the length and width of the midsole, and these are what creates the barefoot feeling: you don’t have a piece of foam to flex anymore, but almost independent “blocks” that adapt to your foot while it moves during the running gait
• There are inserts of soft, durable foam under the forefoot and the heel in order to provide a degree of cushioning where needed
• Sizes available (US women's): 6, 7, 8, 9, 10
• Colours available: green, red, grey & pink, black & peach, and orange

Sizing:

• Size 6: 22.7 cm long (heel to toe)
• Size 7: 23.8cm long
• Size 8: 24.4cm long
• Size 9: 25.4cm long
• Size 10: 26.4cm long
