Vivobarefoot ESC Tempest ReviewWelcome to Swimrun Gear Talk, co-hosted by our friends Annie and Brooke from the Swimrun Labs.In this episode, we break down the Vivobarefoot ESC Tempest Swimrun Shoe. Chris and Chipper have trained in the swimrun shoes for several weeks and they are ready to share their thoughts on the Tempest and get peppered with questions by the Swimrun Labs.(Note: Vivobarefoot was kind enough to send us a couple of pairs of shoes to demo and they have not asked us for an endorsement or paid us for this review.)(Second Note: if you want to learn more about Vivobarefoot and the genesis of the ESC Tempest, check out episode 23 of the podcast for our interview with Asher Clark, Co-founder of Vivobarefoot.)Previous Show Review UpdatesSalomon Amphib Shoe Mini ReviewIn the “Shoedown” episode we chatted about the Salomon Amphib shoe (not the S-Lab version) and Chris has recently have been using these shoes for urban Swimrun practices in San Francisco for several weeks and really liked them. In the Shoedown episode, it was brought up that traction was an issue with these shoes on trails but they have been working extremely well on pavement. Chris would definitely recommend these for more urban adventures.These shoes aren’t in production anymore in the current iteration but the new version is called the Amphib Bold Water Shoe and looks very similar to the version that Chris used.Ark Sports ORNÖ 02 Swimrun WetsuitIn our previous review about the Ark Sports ORNÖ 02 wetsuit, we chatted about durability being an issue since the suit is so thin. Recently Annie noticed that she was getting yet another hole in the armpit of the suit and had to fix it with Aquaseal + Neo Neoprene Contact Cement. At this point, she’s thinking that the armpit wear might be a problem if this suit is used too often.Gear Talk First Impressions ReportsArc’teryx Norvan SL Shoe ReviewAnnie recently picked up a pair of the Arc’teryx Norvan SL shoe at a rock-climbing store and loved them. The upper material is very similar to the Amphib uppers and allows for maximum drainage. The Norvan SL is a trail shoe so the tread had a great grip coming out the water and on trails. Annie now thinks that this shoe is a contender to become her everyday Swimrun shoe. Ark Sports VIGG Swimrun Wetsuit ReviewAs mentioned previously, Chris made an ill-advised late-night purchase and ordered the Ark Sports VIGG Swimrun Wetsuit. He used it for one Swimrun practice and it’s safe to say that he’s hooked. The suit is very light and uses the Running++ material in the legs, back and arms. Running in the suit was amazing. It felt more like running in swim skin than a wetsuit. Even though the suit is thin, the neckline kept water out and the suit was comfortable in relatively cold water (around 56-58 degrees Fahrenheit/13-15 Celsius) even without using arm sleeves. Note: the VIGG does not include removable arm sleeves. The Running++ material repelled/shed water as soon as he came out of the water. After observing the ORNÖ O2 and the VIGG closely, the Running++ material appeared to be a tighter weave that the Running+ and felt thinner. The seams on the VIGG look a bit sturdier than those on the ORNÖ as well. This might be due to all the Running++ material used. The jury is still out on durability but it looks like it might last with proper care.Overall, the suit was amazing and Chris now understands why Annie and Chipper want to use their Ark Sports suits in training despite the durability issues. The VIGG is a joy to Swimrun in and Chris plans to use it in training as long as the water temperature allows.The Main Event: The Vivobarefoot ECS Tempest Swimrun Shoe ReviewThe Tempest is the first style to launch as part of the “Extreme Survival Collection,” and is touted as “the best Swim Run shoe on the planet, for the amphibious athlete” on the Vivobarefoot website.
